Well i can't truly feel sorry for him, she is like this from the begging, he was interested in Miharu, accepted dating her only because she asked first, and asked him full Oshiko mode.
Dude can be awkward and all and the story most probably will show him growing from it, don't change that most of his problems are his fault tho.
Minus that whole curtain thing that we still don't know what is truly about all she has done are things she always showed in her personally from the beginning.
