I wish it focused a bit more on MC like this - I feel like so many chapters are focused on the brother. The draw of this series is 'a straight man stuck in a BL world and trying to avoid the flags', not 'a gay man being in a BL relationship'.
I also hope that the MC does stay out of BL relationships, because again, that's the entire plot, and it'd feel kind of silly to then just have him give up and get into one - though that does seem to be the endgame at the moment unfortunately.
