For the most part, Seven displays a happy-go-lucky, outgoing, and very bizarre personality. He frequently plays pranks on Yoosung in the chat room, makes fun of the other members (and himself), and, in response to just about anything, will respond with a series of "lol"s. He jokingly refers to himself as a god, and has a rivalry with Jumin due to his stifling affection for his prized cat.

However, the player's first impression of Seven is not the "real" Seven. He frequently dodges questions from the other members of the RFA regarding the true nature of his work, using his humorous persona to deflect suspicion. Outside the chat room, and behind the humorous front he puts up, Seven is actually quite depressed and serious, and he refuses to believe that anything good can happen to him. This is due to his past and his profession as a skilled hacker, as he thinks that he will endanger anyone he gets close to. This fear is brought up very often during the events of his route, usually when he is trying to push the main character away. 

Though he rejects the main character if they express genuine affection, it is evident that he values them quite a lot and very readily reciprocates when convinced that they will accept him regardless of how he is. After his route, he returns to his previous jokester self--just a little more grounded, and now more content in who he is without the pressure to put up a cheerful front.

Voice quality: Medium to low pitched. Able to swap between a fun/quirky sort of tone, and serious or depressed.
