Was waiting for the translation to post it.
When I was starting to like this... makes me think this is a "Nagatoro" that went VERY wrong.
What did it matter Yamada having a moment of sincerity, if what she said is really true, in the previous chapter? In this last chapter she again was mean to Hoshino for no reason. Maybe what she said about liking to see him suffer is true, and what this makes of Hoshino? He likes the absuse? What reason does he even has to like Yamada? Isn't like in "Nagatoro" where Naoto is truing to resist Nagatoro and eventually Naoto gets to see Nagatoro's good parts and she pushes him to be better, here Hoshino has not reason to even tolerate to be in Yamada's presence.
And now not only does he likes her, even after not talking with her a single time in the month before she moved, he still remembers and wants to go find her? Imagine the cuckery waiting for him if he one day finds her (not that he would dislike, I imagine).
In the end, a despicable pittable trashy MC.
Everything bad Yamada said about him was true and worse.
edit: no matter how good Makoto Ojiro's next work is, she wasted a godly design with Yamada.
