This story has been on my for days. It's a story about the seme kept on having dreams about his ex(?) Then the uke i think is not a human cause he can go in and out in the seme's dreams.
Ok there’s one more I got https://www.mangago.me/read-manga/the_uninvited_guest_on_my_shoulder/
Only the dream seme has is his crush not ex I think.
