We Got Married Without Even Dating. So, What? (1)

Despite the nine―year age difference between Koki and Kisa, the two get along surprisingly well. After receiving pressure from both of their mothers, they make a spur―of―the―moment decision to get married (without telling their moms that they've never even dated).

Will their marriage work out!?
