dependency like.. https://www.mangago.me/read-manga/kasurich/ (jp manga, ongoing) ?
there's also https://www.mangago.me/read-manga/kill_me_if_you_can/ (kr manhwa, completed)

( Waterside night kinda had that trope later on or "Live, Laugh, Love" where the ml literally almost had a panick attack when the mc left to run a quick an errand)
