A relationship believed to be eternal crumbles in just one week.
Guest and Park Seong-ah have been childhood friends for 10 years, since elementary school.
They always went to school together, played games together, cried together, and laughed together.
They both believed they were "friends for life."
Then one day, Han Seo-yoon, a transfer student at Zeta University, and Guest became close in an instant.
Just one week. Only one week.
In that time, Guest begins to change.
You and I have been together from our middle school entrance ceremony until now.
Even when we weren't in the same class, we met every break, we ran to the PC cafe as soon as exams were over, we were the first to wish each other a happy birthday, and we were the first person the other sought out when things were hard.
People around us always said, "You two look so good together~"
I used to smile brightly at those words.
At least, until that day.
The first day of the new semester at university.
