I don't get it either. I guess writers are just giving FL more tries cuz she's so dumb and still can't get it right 🤣

So why did his watch reset to 3 tries again? Plot device?
I'm getting tired of this time jumping. Now there's a twisted take on "amnesia" and most likely that ain't gonna save him from that dumb blank slate serial killer, cuz he's gonna find a way to pop up again somehow.

FL's so fken dumb, what was even that in the first half of the episode?
SEONJEYAAA, imma save ya! Yea, right, girl can't even save herself even when told exactly what to do. And of course suffering from noble idiocy she thinks saving him is more important than both of the staying safe. What, she thinks ML would cry tears of joy if she dies in his stead?

Anyway, I'm tired of FL's dumbassery, she never learns, flailing around aimlessly. I only hope they won't end with a "it was all a dream" and reset it back to school days, or worse, stay strangers.

Where in ep15?

This drama does show a corporate culture that may feel uncomfortable to the Western audience. Seniority system, workplace abuse, overworking, etc. But it is still pretty much the norm in East Asia, it's not particular to this kdrama. Some countries started to see this as a problem and blacklisting such companies so that newcomers to workforce market would know bad places to work, but it's of minimal help, because beggars can't be choosers, so to speak.

First off, she agreed to continue playing the role of his fiancee and to basically everything else. And it wasn't stupidity, she knew that she was guilty, especially after hearing of her ilness being a misdiagnosis. ML didn't know anything about her motivations, but he knew that somebody was out there to ruin and kill him, and that they may have had allies. So he was right to be very suspicious of her and not calling a police on her was very generous (probably because he already started to like her) - she comitted fraud, owed him more than $700k in property damages and mistreated him.

Second, he really needed that kiss at that moment to hurt his ex and apoligized for it later very properly. It wasn't done because he suddenly wanted to sexually harass FL.

Third, he didn't start to change only after learning of FL's ilness. It was gradual, you can start seeing signs of attitude change towards FL from around episode 6. I already get that nuances are lost on you. But you can't deny that he stopped doing his short contra-revenge on her immediately after he realized he fell for her and he even wanted to ask her on a date, but his blackmailing delulu ex called him at that moment to force him to go to dinner with her instead.
And yea, he was a poor guy in the story - everybody in his life constantly left and betrayed him. From his parents and grandma, to his first employer, his ex and closest friend. Except for FL, but he didn't want to get hurt anymore in case she left him too, so he decided to let her go as well by ending their hostage contract (again, super genereous and FL even admitted to herself she won a lotto) and firing her.

And it was all before he knew of her ilness. But when he learnt of it he knew he couldn't stay away anymore.

So he may not have started treating other people better, because he still didn't know or care about their motivations. But he started with FL. And that was crucial to his redemption arc, because she nudged him in the right direction to become a better man and to start caring about other people as well.
It's a well written plot, very deliberately segregated into parts. The first being FL solving her problem and reconciling with ML. And second being ML's redemption arc, which could not have happened if ML and FL were still at each other's throats.

The problem with your view is that you assume everybody, including ML, knew about her motivations. But nobody knew her reasons and ML was in the right to call a police on her for fraud, $700k in property damages and his mistreatment.
And again, there was no discrimination here based on gender, get your facts straight. If FL was a male character ML would have still bullied him, like he did with his other male workers. But he never expressed any sorts gender based slurs or derogatory remarks, nor did he ever tried to sexually harass anybody. And also, none of his workers were treated worse, or were said to be paid less based on their gender.

Your problem is you're assuming that characters knew of other characters motivations. And again, nuances are seemingly lost on you.
That scene where he denied her audition and the asked her to stay by his side instead of leaving him to be an instructor was selfish on the surface, but he did it because he was terrified of losing her because of her ilness. That's why he also didn't want her to overwork herself in any way, stayed late at night to do the research on said ilness and did all those other nice things to make her comfortable at work and at home. He also was planning to leave his job for her.
But after he saw how passionate she was about being an instructor he gave up trying to stop her and decided to support her by asking his teachers to give her advice and told her there's a second audition coming.

Don't listen to the other person, there was nothing sexist in this drama, that person is confused about definitions. And the example given was a badly chosen one - that situation was justified and could have been much worse if ML wasn't starting to like FL already.
Just watch the drama and make an opinion by yourself. Just pay attention, mind, because there's a lot going on and motives are nuanced.

That's not sexist, look up the definition. ML's nastiness didn't discriminate on gender here - he treated everybody badly, but never in a sexist way. As for what he made FL do according to his hostage contract was revenge on her revenge on him which she pursued in the first part of the drama. He could have done much worse for what she did to him and how much money she owed him in damages, but it was pretty tame and ended very quickly after just one episode. And also, she agreed to basically everything to save her father's property and herself from jail. Furthermore, he apologized for the kiss very properly. I don't know if the nuances of this drama are genuinely lost on you or you just wasn't paying attention enough like some people here, but either way - there was nothing sexist here. Also, you might want to put what you wrote under spoilers.

Sexist where exactly?

What's up with the title? 🤔🤣
It's dreaming of actually f****** Cinderella? Or this Cinderella is so f****** bad here?

Yea, but where would they find a short ML when only tall actors seem to be in demand, lol?
Also, the hell they've been feeding kids in SK in the past decades? Tall east Asians are still a rarity generally, it's genetics and specific nutrition. Where are all these super tall guys coming from? Or do they really select actors by height now as main criteria?
I've read that Netherlands got their populace's average height as the tallest in Europe (+20cm since the 19th century) by adopting lots of dairy products such as milk to their diet, along with generally more healthy, rich foods. Is this it for SK as well?

But he also was in a band in school years. He can play as well.

Yea, but if he were a true serial killer he couldn't have helped himself but to kill some more people since she has eluded him.

The height difference between FL and ML here is just staggering. Probably the biggest I've seen in kdramas. I mean, yea, girls like taller guys than them but it seems to be a trend lately that kdrama ML actors have to be ~2m basketball player tall.
ML just looks uncomfortable kissing her, probably gonna get a hunchback later in life 🤣. And FL being that tiny compared, with her tiny voice, somehow screams loli to me.

I'm glad they finally resolved who rented that video tape 🤣. Poor ML's father was being labeled as a horny weirdo by FL's mom for too long.

It's weird that the serial killer is so fixated on FL, usually they can't control their urges and kill whomever they can conveniently find. He's more like a stalker killer, than serial one. But whatever, couldn't care less about him, he's just a vibe killing dumb plot device.

It's going to be a 5 man band in the end? Or SML will pursue a different career?

It seems there will be 2 female members. The older one being played by Oh Yeon Seo. And younger, looking very similar in character to Krystal's character, being played by Jang Gyu Ri.
