The comment section of this drama is really on fire rn wich makes me both interested and sad. Only giving my honest opinion (also I'm not a native english speaker so pls don't mind my mistakes, thanks): this series has become my safe place recently, allows me to not overthink and just enjoy the moment. It's cute, genuine and in episode 4 has some really realistic dialog in my opinion. Let's think about how Zo was worried that Joke would have felt uncomfortable in that bedroom or before when Joke was tired and put his head on Zo's shoulder: i didn't see those scene like romantic stuff but just like normal human caring. Idk if I explained myself but I think that those kind of lines and actions makes me believe even more in their love story because it feels more real. None of them are embarrassed for unnecessary reasons, the characters also say some sentences that are not connected with the plot (I know it's a silly example but I think of when they were giving the offerings to the monk and Zo was about to forget to take off the glove ) This are little things that help you immerse yourself in their lives. Another thing is that for me Dunk acting in this series is not bad at all compared to other stuff that I've seen from GMMTV and not (for example Joong in SIMM, but if i have to be honest i don't remember if it was the acting or just Kluen that i was hating so much). Also It's not slow at all, it has a nice pace and tbh their relationship is developing really quickly which i don't mind. The storyline of this series is nothing special but is not bad, the only thing that I didn't really understand was the flashback. All this words to say that I'm gonna continue watch this series because is cute, sweet and adorable, if you don't like the couple it's okay, everyone has their own tastes, nothing special. Just stop watching series with them because (surprise, surprise) you're not gonna like it. Last thing, if you're criticizing Dunk for his acting skills only because you find Joong hotter so his acting skills don't matter anymore...honey, have you seen Dunk well? He's hot as hell like everyone else in GMMTV, can we start to appreciate the beauty of this man in these comments or do we only have to talk about Joong's beauty every time?
