Mina and Chaeyoung are married for 15 years. They have a older daughter and a younger son. But what if one day, Chaeyoung needs to meet his new business partner? Chaeyoung is a light producer (which means he makes light). He meets his new business partner and slowly... What happened? Read to find out! Inspired by a drama. Decided to try new things so please support me! [UNEDITED]
