Billy doesn't say anything at all for a long moment, just blinks mutely at Seifer, at a loss for words. Because he has been assuming. Because why would things be any different than they were back home? Because why would Nida...And he hasn't asked, because...

"I'm his best friend," he says, shoulders falling. "It's not fair of me to make that weird, or make him feel like he can't trust me anymore." Because Nida can't really feel that way about him, so what's the point in ruining a good thing he genuinely enjoys? Not to mention all the rest. How much he fucked up.

"Besides, Nida deserves better than someone like me. I'm a really shitty boyfriend," he says eventually. "Just ask my ex." It's...nice to think about, maybe. But it's not fair. Not to Nida.
