Sehun and Subin come from different background.

One is the child of the owner of the mansion, while the other is the grandchild of the head servant of the mansion.

One quite talkative yet the other never let a single sound be heard.

Both so different yet get along with each other.

Both became playmate from the day they knew each other.

Both became the best of friends as they grew up thought both went to different school.

But as high school started and one enroll the same school with the other, the differences start to show.

And that’s when everything starts to change.
