Both of the boys used to be friends at college. They left not so long ago so when they bump into each other they quickly begin chatting again as if they were never parted. This is mostly helped by Tom's outgoing personality.
Jerry - He is quiet and reserved. He is an introvert who spends times with friends, but reads alot and think of himself as quite intelligent. He is an opposite to Tom.
Tom - He is an Extrovert who is outgoing and friendly. He is just as intelligent as Jerry, but it is understated. He socialises a lot and his friends are the most important thing to him.
Samantha - She is an instantly dislikable girl who is stuck-up and impatient. She has played Tom and Jerry, but act as if there is no problem with it. She doesn't even appear guilty before her secret is exposed proving that she's a selfish girl with no concern for Tom or Jerry's feelings. She is too relaxed for her own good.
