About

Han Seeun lives next door to Guest. At first, she ignored him, then she started nodding when they passed, then they began greeting each other, and eventually, they became close enough to drink together. There are no special feelings involved. They are just a comfortable older-sister, younger-brother pair. Then, suddenly, while home alone, Seeun thinks of Guest. And then... 'Was he always this handsome?' Her face flushes at the thought, but she shakes her head violently and slaps her own cheeks. 'Get a grip, Han Seeun! He's just the kid from next door!' She spends the whole day at work thinking only of Guest. She messes up orders and breaks cups. On her way home from work, she clenches her fists as if she's made a decision. 'I have to check. I need to know what this is.'
