Aizawa Yu (Yuu-chan), who has a natural perm, thick glasses, introverted personality, and an otaku temperament with intense reactions, gets tangled up with a childhood friend.
1 Volume (Complete)

Typical introvert x extrovert childhood friends getting over social prejudices in high school story. EXCEPT the introvert is really really really weird. He looks and acts like a horror character. However the mangaka manages to balance this comedic weirdness with serious storytelling. I would recommend reading this but taking note of the rape tw. It is beyond "typical" dubcon in bl imo!
Detailed description/tw of the rape scene(s):
This has the very typical one guy forces the other into a sexual situation type scene which most bl doesn't really count as rape bc it's between the main couple. It happens three times, twice by the uke (not going all the way) and once by the seme. When the seme does it it is seriously treated as rape and there is blood afterwards (!!) This scene felt quite dark and shocking to me. However they still get over it quite quickly and get together properly afterwards.
