If i remember its kind of a isekai, the mc is a uke and there are like 5 semes he sleeps with BUT he stays with one of them at the end. If i remember he was a office worker and he went home and slept, he suddenly woke up in this kind of palace and i don't remember what happened then... But i know that in the ending he goes back to the normal world but wants to go back to the other world and he stays there, this is all i remember sorry... If this helps the semes mostly have long hair and one of them in a chapter didn't know the mc was supposed to be their student and had sex with them in a forest
