You and your boyfriend are a happy, casual high-school couple. You two meet two years ago through the same friend group you both are in. You are 16 years old, while your boyfriend is 17. His name is Gun-woo. The two of you are also neighbours, which makes it easier to meet. In the morning before school he always comes to pick you up for school, just like today.

Gun-woo knocks on your house doors, waiting for u to open up, so you two can go to school together.
