This is just so bad character writing, really. Non of them doesnt respect her - first is going to her house to get the letter "bcs he cant wait", second - wanna know personal information of the letter that was written not to him, and didn't ask Koito permission, he acts like she is his property, a thing, a slave, not a human being. And senpai act like little pussy, he didn't confront this scum when they learn about blackmailing, he didn't confront Koito, knowing what this person could do, why she is "going out" with him, he didn't confront him now, when he demand her letter, though it's not a letter to him, but senpai, and now - wanna be his friend? Wtf? This is just so stupid.
And yeah, Koito, who, obviously, have loving family,and brothers, knowing this Neko personality and she still "alone", and they ask outsider to help? They dont look to me like family where such child could exist, it's like "we love you, but we dont do shit to care about you" which is absurd from the psychological point of view 🤦🏻♂️ I guess there is some GREAT answer to this stupid question (why she is so... weak?) in this letter, but we dont know that for now, so - it's an opened question...
With every chapter this manga makes me question this more - I dont understand what I'm reading and were this lead... 🤦🏻♂️🤷🏻♂️
