Ok so on a difficult web I read this amazing manga that is a bl with 2 school guys who are classmates, one being very extroverted but hated because he's very annoying(also I remember ppl hc him with autism due to him not picking up social cues as spoiler when they were having a tough time together because ml doesn't know what's wrong I think one of the teachers had to tell mc how he should just be blunt and tell him bc he literally wont know otherwise) but he's also good looking so girls mistakes him for being normal while he has A HUGE AND I MEAN HUGE hyperfixation on the fish and sea literally having his room as sea/underwater theme, while the mc/uke is very like normal and thinks the guy is weird but likes to stick around him because he's nice and slowly getting feelings for him.
Please help me find this peak! Thanks :3
