Description: Part 1

Facing a custody battle that threatens to rip his young son from his life, librarian Hwang Chansung is hyper-vigilant, not wanting to give his ex-wife any ammunition to use against him in court.

Kindergarten teacher Lee Junho is fresh off a bad break-up. Meeting the handsome single father on the first day of school is the last thing his battered heart needs, but he's drawn to Chansung.

With the help of Chansung's five year old, Jay, the men start spending time together. Despite Chansung's fears of his uality costing him custody of his son, he can't help developing feelings for his son's teacher. When Jay shows up to school with bruises, Junho is pulled into the court case, and the custody battle turns into an all-out war.

Are Chansung's and Junho's feelings for each other strong enough to win the day or will their love become a casualty in Chansung's fight to save his son?
