“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! Woojin’s company is suddenly in need of a new illustrator and Eunsoo is the only perfect candidate available for the job! Excited at the prospect of working with Woojin, Eunsoo begins concocting plans, confident that a change of place will become the friction that will help Woojin see him in a new light. But Woojin is onto his shenanigans and has no intention of falling for his seductions! Only one question remains now: Will love bloom on the clock or will it fizzle and burn out?
