1000 Years Old

Overview:

Though enigmatic loner Pun has lived an exceedingly long life, he hasn't aged past about twenty-five. Yeah, Pun isn't some ordinary human. He has the blood of what some may call a vampire. Pun lives alone, modestly—like any regular person. One day, he meets a student named Yo. Yo becomes the first person Pun trusts and accepts into his life, and, without either realising it, that thing called love begins to develop between human and vampire.
