Once there was a word ' what goes around, comes back around '. it might have happened to some people, but you, yourself had experienced it.

The words which means ' Karma ' had made your life complicated, yet it led you toward a better life with someone you actually love.

This might not be a drama, where people who hates you would bully you to death, neither this is a fairytale where happy ending would be found.

and this ' best thing ' thing, is just a mere flashbacks of your story with your crush, the bad guy crush called Oh Sehun.
