I think you're talking about this one; he's very deadpan and good at avoiding any and ALL situations

One of my favorites because it's not often that a MC stsys the same throughout
Because I would recommend this one to you: https://www.mangago.zone/read-manga/i_took_a_trip_to_an_otome_game/
It' not TECHNICALLY a bl world but since MC isekai'd into the otome world he's still seen as the "female love interest" so the leads HAVE to treat him that way. And it leads to some interesting developments!
sooo i’m looking for a manga of a guy who lives in a bl world but he isn’t gay and it’s so funny how he’s trying to escape from every bl trope.
Pls if you have the name!!
