Marriage.

That is the word that Yujin hate since last month that Minju married someone that is not her.

It is a lifelong bond, meant to unify a husband and wife. The sacred bond meant to unify lovers. Lovers who love each other. That was the idea of a marriage. But Yujin wasn't in a marriage with love, at least, not mutual love. Perhaps her way of moving on since she don’t want to ruined Minju’s life now. Whatever happens to them is in the past now, though she won’t deny that Minju still holds a special place in her life.
