Story
“When I grow up, I wanna marry you, hyung!” When Woojin first heard Eunsoo, the little kid from next-door say this to him, he chalked it up to childish naivete. However, it turned out to be only the first of the many, many declarations of love Eunsoo would make to Woojin over the next few years. Cut to present day, although Eunsoo’s love for Woojin has remained unchanged, Woojin still thinks of him as the kid he used to babysit. Things start looking bad when neither side is ready to give. But Lady luck intervenes to break the stalemate!
