Choi Ja-Hye is a lawyer and Dokgo Young is a detective with a hot temper. They work together on a murder case where the suspects are children from the elite class.

Jang Ha Na and Choi Won are incredibly close platonic friends: throughout 20 years, they’ve braved it all through thick and thin. As Ha Na’s 30th birthday approaches, Won extols the virtues of aging as a man—like a wine—while explaining that women are like grapes that shrivel into raisins. Determined to prove him wrong, Ha Na strikes a bet on which of the two will marry before turning 35. Based on Taiwan’s hit In Time With You, can these two friends make the ultimate leap?

Cha Ji-Won is a UDT officer of the Navy Special Operations Force. He is positive and has personal charm, but he falls into a desperate situation due to a friend’s betrayal. He goes through numerous life or death situations. Cha Ji-Won then enters into a fake marriage with Swan to hide his identity. Through the bright persona of Swan, Cha Ji-Won falls in love and regains his trust of others.
