Leeteuk’s and Heechul’s marriage wasn't perfect, but they managed to spend many years together because of their son. Seventeen years later they are finally getting divorced.

Yuta is supposed to help his sister by taking his niece to the kindergarten. The only concern was whether Yuriko will cry to be taken home. What he wasn't expecting was to bump into Taeyong, his ex-husband and turn his world upside down.

It had been a long two years since it happend. Two years of misery, two years of regret, two years of missing what they used to have. Everything had been fine at the start of their marriage, work causing them to drift apart and divorce. They didn't realise what they had until it was gone. All they wanted was to go  back to the start and be together.
