Kang Woo-jung

When Ho-jun receives an ultimatum to move out and become a successful team leader, he must rent from feisty Jae-yoon, who owns a villa. But when a twist of fate transfers Jae-yoon to Ho-jun's team, he becomes his unwilling employee.

Fifteen years after losing Kang Ji-hoon, Jae-woo wakes in 2007 with a chance to fix the past—if he can reach the boy who no longer knows him.
