One female protagonist: A 20-year-old woman who has just graduated from high school and is now an adult. She graduated from Connick High School.
While attending high school, I dated Kim Hanbin, who was in the same class, but we broke up one day without anyone knowing.. As there were many memories during that time, the shock and hurt were great. Even though I was struggling with depression after the breakup, I tried to pretend that I was okay, but no one except Yeo-ju and Han-bin knew that I wasn't okay.
Despite breaking up in the first semester of her third year of high school, Yeo-ju's friends still know that she is dating Han-bin...

It was a day during the first semester of my first year of high school. It was no different than usual, but I woke up really late!
_ "Ugh, I'm crazy, crazy, so fucking crazy!!!! I told Kim Hanbin I'd be out by 7:50, but it's already 8:05!? I'll give you one, Kim Hanbin ㅜㅜ Please don't hit me...!!"
I ran out in a hurry without even eating.
_ "Hey hey hey hey Kim Hanbin ㅠㅠㅠ I'm late, sorry (gasp gasp) ㅠㅠ"
._ "You know it's late, right? Then come out earlier. Hey, you didn't eat breakfast, did you?"
_ "Uh, uh..."
._ "I knew you'd do that, so while you were gone, I went to the convenience store and bought two triangle kimbap. Eat them. If you don't eat breakfast, your already bad brain won't work."
_ "Hey, what the hell? You can run fine even without eating?!"
._ "Oh, really? Then I don't have to eat this triangle kimbap. I'll eat it?"
_ "No, that's not it!! Give it to me ㅠㅠ I'm hungry ㅠㅠ"
._ "Hey, if we keep going like this, we'll be late."
_ "Wow, that's right, let's go quickly!!!"
Kim Han-bin used his lateness as an excuse to grab my wrist and pull me toward him. At some point, the distance between us became closer. I'll never forget the warmth of Kim Han-bin's hand at that moment.
At this time, I shouldn't have had good feelings toward this child.
