I think the sister has a brother complex adding with how much she sacrifice for her brother. I think she want her brother to tell her about all of his secret. She did get close and become girlfriend with the actor. Maybe because she want to punish her brother when he lied to her about his orientation, his one night stand, and his crush on the actor. Like I've mentioned, she has brother complex where she wants her brother to tell her everything and wants to makes her brother suffer as a punishment for lying to her.

I think different person can have different taste, but i like this manga. I think the author want to make a fluffy type manga with intensity and a little sex. I understand and honestly hate the twins because of their foul mouth (why people like this still exist :-( ) Their mouth was the one who start all the misunderstanding. I like how author potray the seme as a person who's desperate and understanding at the same time with the uke and the twins. The uke also look so fragile but truely love the seme make this story fluffy. But i honestly hate the twins sooooo much. And i also agreed that this story seems a little rush.
Look suspicious. I can't. MC might heart broken laterrr. I can'tttt
