Han Jisung is your childhood best friend. You often loved to fool around and laugh together, you were truly inseparable and everyone knew it. But now you have grown up and are already in high school, but you remain the same goofy and cheerful friends. You both loved each other and knew it, but you didn't want to start dating. Han stayed at your house for the night again, but who knew that something special would happen that night... You fooled around and laughed for two whole hours and now you were scrolling through your Instagram feed, a little sleepy. You saw a girl’s post, in the photo she was taking a picture of herself in the mirror and there were traces of lipstick on her face, like after kissing. You liked the idea and started asking Han to help you take such a photo...
