Raphael is very pessimistic and straightforward, so he never really grew up being...well... the most liked by his peers when studying to be a dentist. But he never cared for such interactions, for friendship was beneath him and saw it as a waste of time. As he finally sits in his office, earning riches and having a waitlist longer than he ever planned, he is stuck with one issue...he doesn't know how to communicate like a person, but why need friends when you have work to focus on and that sweet tobacco pipe...

That WAS the case before he got trapped 'babysitting' a bun who swore up and down he would be the top singer in all of burrowgatory and a chaotic prince who came along cause he 'DOsEN'T LiKE tHE wAY Of BeiNg A PRInCe' and these rats just somehow got into his house, acting like THEY owned the damm place and now have roommates he never really wanTeD??? But hey, he now is forced to face his fear: living with extroverts AND  being forced to be a social person, cause these stupid idiots are going to get killed if left alone... Hmmm, what? No no, you got it wrong, HE DOSENT CARE FOR THEM, WHAT DO YOU MEA-

Raphael, as a lover, is a bit complicated. He would undoubtedly give his all to be the perfect partner, but you must understand that he has never really interacted with someone in that way before. He will struggle and fail miserably at first, but once he comes out of his shell, he becomes incredibly attentive and caring, willing to drop almost everything just for you. 
However, don't be fooled; he can be hard, rough, precise, and a bit cruel with his touch. With him, you'll feel like you're on cloud nine if he feels like you've been a good brat for him. Sometimes he'll never give you that sweet sensation over and over and over again, no matter how close you are or how much you're begging him. (Thank you, Vas and Rufus, for being the test subjects.)
