Scott: in the time the two of you are alone you forget about all problems and it's the only time he properly relaxes and acts laid back
Stiles: he is still that sarcastic boy with a great interest of mysteries and criminology but that's just another disguise. Stiles is haunted by his mothers death and displays a sadness only you've ever seen because he trusts you with his life and everything going on in his head.
Derek: he's a complete softy and sweetheart and will attend to your every need
Jackson: when the two of you are alone he's not that spoiled kid (except in bed ;) and instead let's down his wall and acts like a complete gentleman
Isaac: he's like a lost boy from Neverland but he knows exactly what he wants and that's you! The two of you can barely keep your hands off each other and are constantly making out
Aiden: Aiden is still that seductive and confident guy but he's also a secret geek. You heard me. Behind those doors, the two of you can spend hours reading in silence while you snuggle into him with his arm around you
Liam: he's scared. His whole life got turned upside down when he got turned into a werewolf and he misses being a human. However he now feels more fulfilled because he's helping and protecting others. When the two of you are alone you play video games and watch movies while eating junk food
Brett: even behind doors he can be quite cocky but he will never hurt you intentionally and puts you before anything else
Theo: he's not that villainy tough guy who will destroy everything that stands in his way instead he shows that he's still a naive kid who got himself trapped in trouble and can't find his way out
