@milk sure :) scrolling through my bookmarks, here's a few that fit the bill in no particular order, sticking roughly close to this one in genre.
MANHUA:
All Hail the Sect Leader
very cute mono romance, though it's a very slow burn and not a big focus
Apex Future Martial Arts
Baits you to expect a harem, then he locks in his hottie teacher and gets married lol. Another cute romance, but sadly very secondary to the story.
Keep A Low Profile, Sect Leader
These sect leaders be very monogamous apparently. dudes max level rizz lord, everyone wants a piece, but he's only got eyes for his badass spear wielding master from his last life.
Very solid romance, that gets plenty of story focus as well!
Throne of Seal
Bit of an asterisk on this one because while there is a manhua, I've never read it and thus don't know how good it is, but I've watched the donghua, and it is incredible. Imo it has THE best romance in an action story, period. On par with, and in many cases even surpassing, dedicated romance stories. Def recommend watching.
