For those defending him, I understand, His feelings or lack of it is fine, I just hate the entitlement of "repaying" her with it. It's a very Arrogant thing and self centered, as he never told her for 6 years they were together. Which is honestly disgusting, he saw her feelings for him as he could trade it, he paid back her sincerity with faked feelings.
He could've told her he had no feelings for her yet and he feels indebted to her and they should start dating to "harness" it, this gives Yoo-min a choice to go through with his "lack of fluttering" and be aware that he is dating but doesn't love her, and she wouldn't feel betrayed
I swear to god of he says to pretend or she does and doesn't correct it imma (╯°Д °)╯╧╧
