Go-Ya

I really like this theory because I also have the feeling that Jeomin is not really interested in a relationship with Do or has romantic feelings for him, which could generally mean that he is not queer and does not have a weakness for guys. That all of this on Jeamin's part is some kind of perfidious game leading to some secret goal or being the result of it.

I haven't read this manga, so my comment is based only on what I've seen and my own reflections. Therefore, there is no doubt in my mind that what we are seeing is the result of some drama, event or arrangement from the past, in which - I wouldn't be surprised - Yeamin played the main role with his manipulative and sick behavior.
If Jeamin had truly had sincere intentions and acted in accordance with his righteous character, he would probably have been in a romantic relationship with DO for years. However, this is not the case and is not the main goal of Jeomin's behavior. I suspect that there is a larger issue from the past at play.
For me, Jeomin and Hye are terrible guys, but Jeomin has an advantage over Hye as he is a calculating and cold-blooded player and is not guided by such hot emotions as Heo. Jeamin is a chess player, he can control his emotions and play the game logically to win. This way, he takes advantage of the situation between DO and Hye and gains some advantage over Hye (I think Jeomin has some hidden goal, like revenge). DO seems to be just a pawn in this game... Jeomin, on the other hand, realizes that DO means a lot to the hot-tempered and demonic Heo, so he proposes a pact where neither of them can date Do, as this is not really Jeomin's goal, but a means to control the situation.

However, DO is either stupid (out of love for Jeomin) or has obligations to both of them. I don't understand why he can't send Hye to the dump if she doesn't want to be around him? Why does she even have to explain his life to him if there is no romantic connection between them?

And as for Juseo, this innocent guy with puppy eyes really loves Do and he's been going through this whole situation like an idiot, and now he's going to have Hye breathing down his neck and probably in trouble. The best thing would be if he just took a step back and left DO alone after that unfortunate but passionate kiss. That kiss, or actually that second after the kiss, probably opened his eyes and showed him who DO's heart really lies with.
Another question that bothers me is why are Hye and Jeomin trying to protect Do and from what?????

or.....Is all this happening just because both gentlemen have a weakness for Do's beauty?

If it was a Thai series I would think that these three had some kind of Phi / nong relationship, something like mentor / junior in student relationships, but this is a Korean series so I don't think it's about that kind of relationship, at least not from Do / Su's side!

since DO wanted to have Jeomin at least once, I think Jeomin and Su shared Do in a non-consummatory romantic way and had some kind of triangular arrangement between them. I just feel like something happened between the three of them.

One thing intrigues me: Why does Do allow all this? Why does he allow Jeomin's manipulation and Su's aggressive and stalker-like behavior? I think there's something else we don't know... Also, remember when DO said he wanted Jeomin, just once? What's really going on here? Why did Jeomin say he shared Do with Su? I think there's a lot of explaining to be done here.

I think the situation looks like this, that Jeamin is for some reason competing with SU, I don't know why, we'll probably find out later. So Jeamin knows that SU loves DO and would like to have him, so in connection with the rivalry between them and the awareness that Do is in love with him, he simply didn't let SU get close to DO..... I'm not convinced if Jeamin is in love with SU, I think it's not love but some kind of sick narcissistic manipulation resulting from rivalry....
However, Do is unaware of all this and probably a bit stupid because he doesn't feel at all what's going on between these two guys, so he's easy to manipulate and to manipulate without any consequences. As for poor JSU, I think he'll eventually figure out this game better than Do and either back down or get Do on his side. JSU is purely in love and has noble intentions towards DO, so he'll probably win this game. I think that should be the moral of this story. We'll see if I'm right.

or maybe it will be as the proverb says; where two are fighting, the third one benefits, and here I mean Jun Seon?

OMG, this series has tired me out. Just boring, badly acted, tough as chewing gum and on top of that there was that idiotic time jump and a three-week visit to Korea after a long break.
Even when UH and DH met again, there was a feeling of coldness and unease between them. What kind of love is it where there is no warmth between two people, no need for closeness?...
The straight couple was the only authentic couple in this idiotic series.
I don't want to remember the teacher's strange behavior towards his U Hyeon. The teacher knew full well that UH had romantic feelings for him and yet he let him get so close and kept giving him hope as if it was his intention. I don't know, but it seemed to me that the teacher somehow reciprocated UH's feelings and was waiting for him to graduate to start an affair, that's how I honestly felt. I saw the disappointment on the teacher's face after his last conversation with U Hyeon.
Maybe the idea for this series was good, but the execution and acting were just terrible.

I don't know, but I just find the whole story boring and I feel like it's dragging on and that nothing really happens in these last episodes. I also wonder who decided that the three couples should behave similarly, that is, that the younger part of the couple should actually act like kindergarten kids and not like boys in college. This is a strange quirk of this series and a little indigestible for me. Beagle/Santa acts like a spoiled and naive preschooler and lets his BF pat his head like a baby. It's a shame that Jotha doesn't change his diaper... and this couple has sex?... it's hard to believe. The other two couples are based on a similar idea. I don't understand what kind of stupid scenario this is? If the action had taken place in the first years of high school, it might have been somewhat acceptable, but with college students?
Actually, Aou and Boom is the only couple I like in this series. They behave according to their age and have temperament and authenticity. The rest is childish and like an unrealistic fairy tale.
I saw that everyone is shouting for Faifa and Wine and I don't understand that either... In my opinion, Wine looks terribly uncomfortable and as if he doesn't like Faifa's advances or as if he simply doesn't like men, which is possible. Faifa is pushy and won't give up.....

exactly, something like that and wise Est knows that the information that he is single shuts them up and clears their brains of imagination. Well, Est and Willi are not innocent and are probably normal healthy guys, what their partnership is about is their business whether it is just about work or friendship or something more. Est is single so there is no discussion. LOL

I know that Est is an athlete because before he was an actor I already knew him from swimming competitions and that's how I came to WilliamEst. What I wanted to say is that saying that you are single (I don't think he's lying) kind of closes the door to hating and making a fuss, kind of cuts off discussion and protects both him and Willi, because many people ship them and Willi is an idol.

After watching this episode, I now understand, literally and tangibly, why Est claims to have been single for eight years. Such a statement guarantees him peace with fans and protects him and William from unnecessary gossip and nosy fans, while also pleasing everyone from delusional solo fans to homophobes.

I don't know how it will end, but I hope it will have a happy ending. I can't imagine this crazy series would end in tragedy. I hope our lovers will somehow stay together or that Sangmin will return to Thailand once his memory is back to the point where he can remember D.
I also have the impression that Sangmin's family in Korea is taking advantage of the fact that Sangmin lost his memory and that's why they brought him back home. Sangmin's mother's behavior was very mysterious; instead of being grateful for taking care of her son, she started fights with D's mother. This is very suspicious. Maybe it's about business or money. Whatever....
However, Sangmin will return to Thailand and support D and Mom financially. This is my prophecy.

I like the Perthsanta couple visually, but I still don't see/feel the chemistry that other couples have. Maybe they are not ready yet or they feel a bit uncomfortable after changing partners, I don't know, but something is not right between them... in my opinion.

Yes, that's exactly what I mean and it seems to me that the plastic surgery that was supposed to improve the face of the person undergoing the surgery didn't quite have the desired effect on Santa this time. I also wonder why he did it?

no, not at all. I haven't seen anyone who would really fit in with Perth. Perth is very special and hasn't really had chemistry with anyone, in my opinion.

no, neither Perth nor Santa suited their previous partners in my opinion

can you tell me why? I expected something great and unfortunately I don't see any chemistry between them. Ok, maybe it's because of San's idiotic role in this series, but somehow they didn't convince me in general.

wait, did I understand that correctly; Gun saw Yotha kissing Wa in front of the toilet (let's add that he had kissed Gun a few hours before) and later he witnessed a fight where Yotha showed all his aggressiveness and several guys, including Yotha, got beaten up. Gun was so devastated by the kiss and so scared by the fight that he didn't want to have anything to do with Yotha anymore and even went back to his room.
But when Yotha confessed his love for Wa during a walk with Gun on the beach and said that Wa had broken up with him and his world was falling apart, Gun suddenly changed his mind 180 degrees and declared that he would wait for Yotha in the hope that he could fall in love with him. Gun decided that he would wait a day, a month, maybe even a year for an answer. How idiotic is that? This is utter nonsense, what utter nonsense. Especially since Yotha said that Gun could leave him without any problem if he love someone more than him. This showed how little he cares about Gun and that he is simply indifferent to his feelings.
What an idiotic plot and idiotically written characters. No way

I think exactly the same thing...who writes these stupid scripts and character profiles? It's annoying and stupid and unrealistic
