Lemme think... can you also read webnovels? I'm very familiar with gaming/esports BL webnovels but not very much with manga/webtoons. There's also one very awesome shounen gaming novel with a manhua adaptation called Let Me Game In Peace, but I haven't read the manhua version.
The best BL esports webnovel imho is Is There Love At First Sight in Esports which also has manhua adaptation, which is a censored shounen ai version of a smut novel: https://www.mangago.zone/read-manga/is_there_a_love_at_first_sight_in_e_sport/
The webnovel translation can be found on novelupdates.
Give me some Game related BL recommendations hihi
