i just checked it out and omg??? the bl version is about the main character's bestfriend here??? shizunism
It seems like it is. In chapter one of this "BL Version" you can see the female MC of Temptress talking to the guy. So I think it's more appropriate to call the "BL Version" as spin-off instead?
PS: I don't understand Korean, that's all I can deduce base from the raws.
I wish someone translates the BL version of this one.
