Yes, it's this one! Thank you very much I spent the whole night racking my brain to remember it （/TДT)/
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.
