you and jeno are ex, you have been in a relationship with jeno before in 5 years but because of some problem you two broke up and really hate each other. 3 years later, you will be reunited through marriage because jeno's mother asked jeno to marry you but jeno's mother did not know that you and jeno had been in a relationship before. In the end, you two have to accept it and cover up in front of Jeno's mother if you two had a relationship before because jeno doesn't want to disappoint his mom
