the story would become more dramatic if someone else was also getting involved. it's also possible that the blonde would just use him. like, theres many possibilities that would be put here if the story become reverse harem. one of them could grape ideum for some reason, like thats what other bl author does to their stories.
Ikr!!!!! I love me a slutty uke.
It would've been a NO NO!! if they were in a relationship. But jaeyi(ig) clearly said they're gonna be JUST FWB and no strings attached. Also, that they can fuck others if they find them attractive.
Tbh, I really don't like the brother(cause I mean, as a sibling, I would never be able to fuck the same person my siblings fucks/think about it) but I do want ideam(ik i butchered both names) to fuck the brother out of his own will....I really really like a slutty uke, especially one that's been a virgin previously.

The people who get mad at the thought of uke see or fuck someone else are the same type of people who get attached to their FUBUs Let Ideum get that dih!
