Idk about an anime, but there's a manhua that comes to mind. Maybe Moritat?

I think it's moritat. You probably thought he had white hair since it wasn't colored xD
I remember clearly it was an anime but thanks :)
oops. it just sounds like moritat tho. maybe an anime clip? i remember that someone made a noblese anime version so you might've seen that.
I will take a look at it :)
Hello everyone! There were two guys standing behind a cliff, and X person said "i am gonna kill you" something like that, and Y person (he had white hair) said "i would prefer to kill myself to you kill me" and then jumped off from the cliff.
