Chiyun and Dongho are two different people, so when they start writing letters to one another, they never expected love to come with it.

Nice guys finish last, That's why I'll treat you like trash, It's not what I really wanna do. But, you only date bad guys so, I'll give it my best try to, Treat you the way you want me to.

You have been cordially invited to the wedding of Mike He and Annie Yue. --- Chiyun was a successful wedding planner, but ironically she hated weddings. All she wanted was to find her Prince Charming and weddings reminded her about how she didn't have one...yet.  

We really don't know what we have until they're gone. We take the people we love for granted, you can try to deny that you don't but you do. Even unintentionally. Tell the people you love how you really feel about them, show them how much you care because you never really know when their time has come.
