Hi,

I only read the first chapter, the main characters live together but don’t have a romantic relationship. The Alpha sleepwalks and when he does he bites his Beta roommate on the neck, but he never tells the Alpha what he has done. This leads to the beta becoming an omega.

I lost the manga and now i can’t find it. Hope someone can help, thanks.

The description seems to fit perfectly with this Banana Fish doujin, Banana Fish dj - Umare Ochita Hi wa Ame .

If its not it, then I have no idea. ( ᐛ )و

ive got a disease called having a big brain and excellent taste.

I rarely update my lists by this point.
