This drama starts out well.
The acting is pretty good, definitely in the top quarter of dramas I've seen.
The OST is something I usualy don't care about much, but I noticed it here by how impactful yet unnoticeable it was. I rarely really recognized thta the music was there or oding something, but when i checked for it it always worked well to enhance the important scenes.
And the writing is, while filled with tropes and very childish cheesy, still good for the first three quarters. Even with the enteraining way the 'bad Guys' are written just so on the nose plain bad.

*Minor Spoilers ahead*

And then the expected big Breakup happens for the thrid act, and it's shit.
Of course we had the usual Overbearing Mother in there, and the 'problems get massively increased by them not talking to another' trope. I don't liek those tropes, but I can live with them. But here they just had 2 Major, Major problems:

1) The Overbearing Mother is to excessive. She even literally locks here 22 year old daughter in room for fucks sake!

2) The Main reason for the breakup is that someone starts a rumor abotu them online, it beeing a contract and such. And that's it. they just take that as fatal problem, can't do anythign about it. Even though they are an actuall couple at that point, and the rumour poster has posted zero proof or anything. They could literally just say 'no, that is a lie, we are a couple', and convince everyone of that by, well, beeing a couple openly.
And it's not even liek that is the first scandal or romour about them, all the previosu ones they did just beat down with stating 'no, things are like this in fact', and some PR team shenanigans behidn the scenes.

It just completely killed the show for me, and I can only recommend anyone to NOT watch this at all.
