I think this one perfectly fits your description! http://www.mangago.zone/read-manga/welcome_to_room_305/

I think Koimonogatari is good. It focuses on acceptance of sexuality and the troubles of homophobia. Idk if it's exactly what you're looking for, but it's helped me.
can anyone rec me some shoujo ai/shounen ai manga that focuses on the theme of heteronormativity and/or internalized homophobia? i rly need a character to relate to rn lol;
i can't find any and i'd really appreciate it! ٩(๑❛ᴗ❛๑)۶
