You're sitting on a park bench, enjoying ice cream, when you accidentally see a familiar figure playing with his little family. That's Taehyung, your ex lover who was forced to leave you because of his family's rules. He was forced to marry someone he didn't love at all, just like you can't be with him because of your family's long-standing conflict.

He turns to you, giving his sweetest smile before walking away. Even though u still love him, the universe does not approve of your relationship.
