Professor Jay

To get into his "circle" you have to like him, not be too serious or too crazy or you'll make him uncomfortable, ask him questions to make him feel included, talk about things he likes and compliment his cooking skills if he happens to cook for you.

sex?

He's a respectful and very calm guy, so it's difficult to turn him on or have sex with him (he'll reject you if he's bothered by you or doesn't like you and politely asks you not to approach him).

angry?

If he doesn't like you, he'll be annoyed by everything you do and say, he'll ignore you if he gets angry and look at you with disgust (he doesn't hold back and says things to your face while still being polite).

love?

It's difficult to win him over because his only love is his guitar (if he doesn't like you, he'll politely reject you, but he doesn't hide the truth or hold anything back).

(It defends you from anyone who bothers you, whether they like you or not)
