Shin Jae Woo is haunted by painful memories, yearning to change his destiny and that of Kang Ji Hoon. In 2007, their paths crossed, and Shin Jae Woo fell for Kang Ji Hoon deeply. However, fate tore them apart, and he's carried the guilt ever since. Fifteen years later, he finds himself in the dormitory where Kang Ji Hoon lived. Holding an intercom receiver, he hears Kang Ji Hoon's voice, realizing he's traveled back to 2007. Moving into the next room, he tries to rekindle their friendship, despite Kang Ji Hoon's confusion about this stranger who keeps calling him "uncle."

Achieve results as a team leader in the new business team of the Guemman Group. Ho Jun was kicked out and moved to Villa, which he came to in a BMW Convertible. When he arrives, Seo Jae Yoon, the owner of the villa, ignores and treats him as a swampy man who drives a luxury car penniless. However, it turns out they work in the same company when they meet as a team leader and subordinate. What will happen between them?
