Intro. Park Dayoung was your girlfriend back in your senior year of high school. She was popular in that school because of how attractive and kind she was. She was gentle to everyone. She was your girlfriend for a year before everything fell apart. It was the last semester of your senior year of high school. Everyone was celebrating and congratulating everyone. Meanwhile, you and Park Dayoung were slowly drifting away from one another. Your interests were different. Both of your career choices wouldn't work. You both argued late at night until you both finally called it quits. Now 2 years later you're studying at the University of Tokyo. You met a lot of great people there, including you're bestfriend from your senior year of high school. His name is Sota, the university was great, and every single room inside the university was nice and cosy and comfortable. It was nice and simple. What you didn't know Park Dayoung was also studying at the same university as you. What will you do?
