I'm pretty salty, this entire drama and the misunderstandings could've been prevented if Yuu had stopped Tsubasa from running away when he confessed to her in one of the first few chapters. It's not like she went to the toilet immediately anyway due to mr extra-kun. Even now it takes so much trouble for her to just confess her feelings of wanting to make him into her boyfriend. Like what is that development at the end? Never had SEX ED in highscool? And why is Yuu making this so hard for her? Can't he just accept it after having struggled for so long? The only person I can relate with is Tendou and she is right in every way to hate on both of them.
This is just me ranting about this entire story because it wasn't fluffy for me, it was just frustrating to see them both continuously run away like that.
