help meee

help me find this manga, i read it about 8 months ago and i cant remember the title or like most of the plot BUT i do remember that the mc is the top and like one day, he finds like an incubus on his apartment (?) but the incubus is like the clumsy, inexperienced one (?) and the incubus appearance is like not the sexy type, its more like a nerdy, hair covering his face kind of type (? even more question mark)

OKAY CAN YALL TELL WHAT WHAT THE NAME IS OR IF YALL KNOW, im trying to make sure what i saw is not a fever dream T___T
