I don't have a problem with this arc. Trap boy is likeable and I won't be bothered by whatever reasoning he has. I don't judge people and just urge them to be themselves. It doesn't affect myself life at all, so why should I care what others do with theirs? Plus, you can't focus in the MCs relationship the whole time. That's how you end up with an extremely short manga with a slew on uninteresting side characters.
