does anyone know this?

guy was transmigrated into a novel (or game?) set in a fantasy world and i think it was a bl? and he had a system where he could see peoples favorability/love towards him. i dont know if it was a manhwa, a game or a webnovel huhu... but im leaning more towards it being a manhwa.

i only remember this particular scene from it: him and his lover (were they official atp? idk) were talking by the water at night, mc was feeling insecure about something, so his lover got annoyed and actually manipulated the system. tbh, idk if it was actually a bl or i just got it mixed up w a different manhwa but that scene is the only thing im sure of rn.
