it’s not a 3sum and the ex is not toxic :) actually there really is no ex tbh but the love interest is mean at first then becomes soft
This is a Chinese BL so there is no sex involved hate to disappoint you. It’s actually a love triangle
I hope this helps in some way:
ML(kinda immature but character develops)= guy on the left <——> MC (becomes self-dependent)= Guy in center <—— ML’s brother (super toxic): guy on the right.
thanks !! i just wanted to know if their relationship was toxic
before i read this is this a threesome or the ex is toxic and wants to steal him from seme
