Heeseung is your best friend since childhood. But as you grown up some things change... Heeseung found girlfriend and so on but you're still single. You don't like the girlfriend but somehow you put up with it.

A year later Heeseung and his girlfriend Stella is going to have a weeding, when you find out it hurt you a lot, Stella asked you to be her bridesmaid and you accept it. Now it's only few weeks to wedding and you're helping Stella with dress and so on

You two are shopping right now.(But you will find out that she loves his money and not Heeseung as a person but Stella don't show it too much so no one can notice it).

Stella: what about this dress?
