DEFINITELY esteemed person/protector and other variation of it (royalty/knight, for example). there's a certain charm where the protector realizes that their need to protect the other no longer just stems from their loyalty and the esteemed person fearing their protector's safety more, if they havent in the first place, because they grew to deeply care for them and is even devastated at the very thought of their death. its the melodrama of it all /laughs

aside from that, i love enemies to lovers, MONSTER/HUMAN, the :D!!! w/ the >:T, where chara A orders around chara b who grumbles but does their bidding bc they dont mind at all, mutual unrequited (bc they're idiots), the couple that tries to hide they're together but failing hilariously (and vice versa where they don't even try to hide it but others still think they arent dating), and some others that i cant think abt jcnakma. it all depends on the mood honestly hahaha
