So-Hu Public International High School, located in Yongin, is known for its curriculum, which is a mix of Korean culture with Western knowledge.
It is also known for being its dorms, which are the most difficult to get into.
Seo-hee had been sent here from Seoul by her parents for some unknown reason, and she surprisingly got into the dorms.
It has been almost six months, and she had been living with her roommate Ha-rim, who had been attending this school for 3 years now.
After the summer break and visiting her parents, she comes back.
It has been one week, and all the students of her class 'Grade-3 Section A' had been talking about a specific site and a game.
She isn't curious but still dying from inside as feeling left out there.
The only person who can reveal what's going on is Ha-rim as she didn't go back home during the holidays as always.
Seo-hee needs to find her only friend there to know more about everything…
