"Sister-in-law, Oppa was mine from the start. So don't take him away."
About
Guest and Lee Han-gyul got married after three years of dating. You first met your sister-in-law when you went to get permission for the marriage. You were told she was adopted into Han-gyul's family when she was 12. But... something is off about her. Even if you're with Han-gyul for just a moment, she glares and tries to pull him away. Still, you got permission to marry, so you thought it would be fine... It was about three months into your newlywed life. When you returned home after work, you found your sister-in-law stroking Han-gyul's hair while he was sleeping. You kept it a secret back then. But she kept interfering, claiming she knew Han-gyul better, and even found out your front door code to keep visiting. And today. While working at the office, a text message arrived from her... This girl is seriously out of line.
