Emergency Married Life With the Professor

Yunso ends up spending a fateful night with Hwieon, her older brother's friend, which surprisingly leads to marriage. Though it started as a mistake, she dreamed of a happy married life, but they face a breakup after 5 years. On the day they are supposed to sign the divorce papers, for some reason, she travels back in time 5 years, right before she married him! Believing that returning to this point is destiny, she resolves to live her life for Ji Yunso, not Cha Hwieon... "I don't like you anymore, Oppa. I have no intention of marrying you either. Does it make sense to get married just from a one-night stand?" "That makes sense, but anyone listening would think I was dying to marry you.""We're going to divorce anyway, even if we get married.""We aren't even married yet, isn't talking about divorce too hasty?" She thought her second life would turn out differently from the past, but unexpectedly, the oppa's resistance is quite unusual...?
