Hot sex scenes. Business partners live together, one gay and one straight, but then one day the straight guy starts initiating sex in his sleep and wakes up to not remember what happened. Finally, he realizes what's happening and starts to take medication for it but he feels like something is wrong and add that onto jealousy when an ex starts hitting on the gay guy and he finally starts initiating sex when he's awake and lucid too. I really enjoyed their relationship at the end. This manga had a slow moving monologue that makes it feel moody.
