A mistake's feed

So, I've just finished re-reading Sensei, Mou Dame Desu, and I absolutely fell in love with the love interest.

I wanted to ask you guys for BL recs with a similar looking love interest (Short hair, quite muscular complection) or a similair personality (Quite clueless, cold, but also when this facade melts starts being shy or embarrassed).

Also, I'm mainly reading BL manga, and that's what I'm trying to find.
