Sounds like this - http://www.mangago.zone/read-manga/aniki_no_ichiban_oishii_tokoro/
i think they were brothers and the older one was attractive, famous(?), and good at archery, but he's a slob and messy. So the younger brother cleans up after him at home, wakes him up and things like that, so he thought his older brother would be a mess without him. Then their parents told them they should be more independent or smth so one of them moved out(i forgot who) then the younger brother realized that it was actually him who can't live without his older brother.
