First of all Jaehyuk is portrayed as new to the idea of bisexuality. Some people dont consider it once until they get in a situation where they feel safe to explore it. Speaking of experience.
Secondly being bisexual doesnt mean you fuck everyone around, so in BL, yaoi of all things you wont see much more heavy rep of bisexuality, it changes its whole tag.
Third of all, this is fiction so everything that is written is part of authors work. Garam disputes Jaehyuks stupid joke. By the plot, at this point Jaehyuk does everything to just make Garam focus on him. I think he is genuinely written as xyz-person-sexual, not so much bisexual or gay. (But he clearly is not straight either and i fkn hate labels, you should fuck whomever you want with their consent and ability to consent, but that is my bisexual bias and not everyone can fit in the labels)
Fourth of all ITS BL, HOW ARE BL WRITERS OBLIGATED TO WRITE BISEXUALITY. Bisexuality by its nature does not fall strictly in BL, it is just adult fiction with BL or GL elements.
It is sexual fantasy.
And
Its
A
Joke
And yes i care cause it does not trigger one bit bi-erasure-phobia.
There you go. Bye ٩(๑❛ᴗ❛๑)۶
bl authors are gonna go crazy when they learn what bisexuality is
