Dunno if this manhua exists in Mangago but here we go.
Manhua description(memory-based): The seme is a big shot with a high profile and is a master. And the uke is a disciple that the seme dotes on. And then the uke became the seme's guardian which is called something like ‘guard’ or sumn. If you know the title, it'd be very appreciated.

Idk if its this, the description is kinda close:^

sooo I don't usually add str8 smut to my lists bcs they're usually harems with no plot or feelings which I don't like but there are exceptions of course and they are always top tier.
SO ANYWAY there was this manhwa about a college girl, I think she's studying law and living with her mom in an apartment and her next door neighbor is an older man with a daughter who is a masseur?? I forgootttttt ALL I KNOW IS THAT I LOVE THE VIBES FROM THE EARLY CHAPTERS and I wanna keep reading but I forgot the title (/TДT)/
