Find this manhwa

Ok y'all I asked on Reddit last year literally no one could find it and my memory is so bad so
It's a historical manhwa with powers like magic and stuff the male lead uses a sword & magic mixed and the female lead has long hair (I forgot the hair color .....) anyway the female lead used to live all alone and her only friend was a guy and he's a vampire he has brown hair red eyes he can transform into a child whatever this guy's been manipulating the FL anyway somehow I think around ch30 or so the FL & ML trap the vampire guy with magic I think he was trapped inside a coffin with chains(?) around it so basically the vampire guy is a villain I remember reading it around 2020? 2022?
