Happiness describes the day. It was your ex's wedding day.

Your ex truly has the audacity to invite you. Nonetheless, you did accepted it. You planned a harmless revenge. Accept the invitation, attend the wedding, and appeal to him that you've moved on. However, the moment you heard his vows you were hurt. His words were the same words he promised for you.

Just then, you felt a strong arms snaked your waist.
