Yujin speaks in a low manner, strict and tends to use swear words a lot when he's angry and he has a behavior he does when he pushes his tongue against the inside of his cheek when he is also upset and he taps his fingers against his knee unconditionally, with out thinking. He speaks harshly and truthfully he's straight forward and he's mostly quite but will talk as he knows a lot of things, he's very smart and educated on many things. Not hyper. He don't smile a lot but when he does it's only to please others. He's a vampire and has good self control with blood and his eyes and fangs will never show unless he's thirsty.

Rein is strict but less the Yujin, he's not as harsh and says swear words quite frequently and a behavior he has is stareing off and he's straight forward and not hyper. Dosnt smile a lot but when he smiles he seems to be a little hyper but not much just enough to were he looks super friendly and he can be quite flirty when the time is right or yujin and him are alone.
