help me find this manhwa!

i can’t remember what it’s called, but the fl is a mage (i think?) and the ml is a dragon. they get together early on in the story and there’s this whole thing about him not telling her about being a dragon or something to do with dragons and she’s really pissed. the ml has black hair and im pretty sure the fl has brown hair. i read this a while ago and its completed, but ive been searching everywhere and can not find it! please help ╥﹏╥
