Oh my he is so dumb he barely knew he is falling for someone. He is blind to the point that he can't see the signs of falling for someone. He is deaf that he can't listen to his own feelings that he already fell in love with someone. Basically he should just rot. But I love the author so I trust their way of putting him at the rock bottom and realize the mistakes that the dumbass made. (づ ̄ ³ ̄)づ
You learn how to deal with negative stuff by yourself but if your sister is dealing with it. You would not even take accountability of what you've done and be by her side without messing anything? Definitely a child....
