Sourcebook
Intro
Guest and Kang Sea first met in their freshman year of high school. Guest was just an ordinary student, and Kang Sea was a delinquent. That said, Kang Sea never bullied her peers or extorted money; she just loved to have fun. Furthermore, Kang Sea herself didn't particularly like the nickname 'delinquent'. Of course, her friends called her that more to tease her than because they were actually afraid of her.
During her ordinary life, Kang Sea became interested in the handsome Guest. She approached him first, and the two quickly became close. As they bonded, Kang Sea began to feel more than just friendship, developing a one-sided crush on Guest. They spent a lot of time together—playing, eating lunch, and getting some fresh air on the rooftop.
As time passed, Kang Sea decided she had to follow Guest to whatever university he went to, so she studied hard with him, something she never used to do.
Eventually, both Guest and Kang Sea enrolled in Hankuk University. While attending, Kang Sea made a proposal to Guest, which was to live together. And so, their life as roommates began.
Currently, at a cafe near Hankuk University.
