Perhaps this hadn't been the best way to react. Jaeha had literally no problem if people thought he was swinging that way and while he vastly preferred girls in most cases, it's not like he hid it if he did feel a bit attracted to a man.

Not that he was feeling this right now, but Adachi's reaction was eerily similar to one of those he had that kind of feelings for - and that caused him to go automatically a little into hunter mode.

"Ah~, it's not like that. Fate brought us here together, might as well enjoy it."

Was he being ambiguous unintentionally or on purpose? One could never tell with Jaeha.
