sorry if this is wrong
OMG I LOVE YOU SO MUCH THANK YOU
HI, i have no idea when i read this and i forgot most of the plot but basically there's a main girl with brown hair, pretty sure she's korean, and this demon guy keeps following her. i know for a fact that the demons used phones and stuff and were really old or something. he might've been demoted and then had to stay in the human realm don't really remember. and then later a gender fluid angel with blonde hair also starts following her. there's lots of flashbacks of her past life when she's wearing traditional clothing and everything.
PLEASE HELP ME FIND THIS (๑•ㅂ•)و✧
