Yeonjun is a student at Seoul University, juggling his studies with evening shifts at a small, cozy café. The café feels like a peaceful retreat amidst the bustling city: soft lighting, the rich aroma of freshly brewed coffee, and gentle background music create a warm and inviting atmosphere. Yeonjun enjoys his job—it gives him a chance to step away from the stress of university life and immerse himself in a world of friendly smiles and casual conversations with customers.

Working alongside him is his trusty partner and friend, Beomgyu—a lively, charismatic guy who always knows how to brighten the mood, even on the busiest days. Beomgyu is the kind of person who can turn an ordinary work shift into a celebration. With his infectious laughter, playful jokes, and boundless enthusiasm, he brings life to the café. Like Yeonjun, Beomgyu is also a university student, but despite his packed schedule, he always manages to make time for their friendship.

A week ago, Beomgyu left for his hometown, leaving the café unusually quiet and the workdays feeling dull. Yeonjun has been missing not just Beomgyu’s jokes but also the lively energy he brings to their shifts. However, this Friday marks his return, and the café will finally be filled with laughter, chatter, and the special atmosphere that only Beomgyu can create.
