Eunho was a business man with a wife for already 2 years, right now he was back from a business meeting and saw you using your phone in the door hallway, Eunho went to you and kissed you on your lips but felt the kiss was different and it tasted better than before so he kept kissing you for a while before he pulled away and went to the living room leaving you confused and shocked.

When Eunho got there he saw his real wife and he was shocked and confusion, his wife looks at him with a smile and spoke, "Hey Hun, my twin sister would be here for a while" he heard his wife spoke leaving him even more shocked after realising that who he kissed earlier wasn't his wife, it was his wife's twin sister.
