No, Author said he IS 8not was) 100% straight and only had GFs before
and then went on to say "it is lockerroom culture" when referring to Eunsans past in which he jerked off other guys/with other guys in the locker room. So even before Ian he was NOT 100% straight as this stuff happened in his teenage years
Bro ur actually so sped ur second paragraph in the initial post literally contradicted ur whole point, talm bout bi-erasure i would agree w ur point if u aint say that dumb ass shit. It isn’t bi-erasure if the author is openly illustrating a character that literally just found out that he likes dick like 2 panels ago.
girl. he "found out he liked dick" in HIGHSCHOOL when he JERKED OFF other guys
Im not saying dumb ass shit u just dont get my point then, like i said, he was not JUST interested in dick after getting fucked by ian??? dumbass he was just in denial if anything. And author-nim went out of their way to tell us "nah hes 100% straight and only had GFs before, he "just jerked off other guys because of lockerroom culture" and im telling u there is no such thing as locker room culture = jerking off the homies while being "100% straight" sybau

"Eunsan is 100% hetero and only had GFs before, he only jerked off other dudes because of lockerroom culture and had sex with a cis man because...not gay! totally not gay or bisexual whatsoever !!"
Like girl...call me the friend thats too woke but thats just asian authors doing bi-erasure again come on.. U can be bi with a preference for girls?? I asked my hetero friends and all of them said they'd NOT jerk off another dude just because of lockerroom culture, and my bi friends were like hell yeah if im attracted to them why not
So like.. I really hope this is being explored more in s2 that eunsan can come to terms with his bisexuality bc im rlly tired of these BL tropes where "ofc they are 100% hetero but just yk a lil exception haha.." like bro come on
