Some people "advice" those who do not like noona romances (even less when the age gap is SO big) to not watch…
well, it's odd to spread negativity even before it starts to air, the romance likely won't even be there, and the age gap... he's not underage, couples like this exist and if someone is triggered, that's fine, but it's nothing terrible
One thing I disagree on, is how people in the comments find Yoon Jin's actions and hatred making no sense. No, people can be just "sick in the head" or literally evil and not have a true motive to hate someone and makes their life hell. Even if the story was different and Jae Won would willingly sleep with her ex, this behavior would not be normal and we all know how many crimes in the world are done without reason or for jealousy ect, it's not like it's bad writing, just cause she doesn't have "valid" motive.
to people complaining about romance... if there is some, only a little bit and maybe it will be even important to the story and all that, so this kind of thinking is childish
