I’m a little confused, is Chihwan still a vampire or did he turn into a human?

he's human. He's Sooin's link.
Sooin is a vampire after ChiHwan lost his powers trying to save Sooin... something like that

hes human

He turned into a human and became sooin's link

I think he died (or on the verge of death) and brought back as a link he came back as human. I may be wrong

I am also confused
