my description of the manhwa is gonna be messy because I don't know how to word it but here goes: • some guy in ancient clothes appears in front of mc, let's call him mc2 • mc2 has long hair, his colour is black (as in his clothes, hair etc are either black or white) • mc2 wears a Korean traditional style mask if I remember correctly(his face is covered wither partially or fully) he also wears Korean traditional clothes • mc2 and mc had some sort of past relationship that mc does not remember • in present age, mc2 acts as his(mc2's) master from the past. so that means in the past, mc was mc2's master, but something happened and mc2 took up his master's role and convinced everyone that he was the master • there's probably a quite a few fight scenes • I dont remember romance being one of the genres • I read this quite a few years ago I'm sorry, the phrasings are a little confusing, I'll be very grateful if you could tell me the title! ><
