The wedding was in a rural area, so it was hard for her to make it there on time. But luckily, Hwasa made it there on time. But to make up for her sister for the inconvenience, now she has to be her sister’s servant for ten years. Telling the story, the idol got done with baking her cake. Decorating it with her sister’s name, she sent a picture to her and apologized for almost getting late to her wedding. As Hwasa appeared alongside Henry Lau, looking at the chemistry of the two singers together, fans were confused. Thinking if Hwasa and Henry were related and actually sister and brother, the two kept on bickering and reused to make up for the longest time. While Kwang Kyu begged them to stop arguing, the two just continued to yell at each other. While Henry gave in first and suggested they make up, Hwasa didn’t change her mind until the very end.
