Han Jisung is the guitarist in the band of your school. One day you were walking around your neighborhood to buy a few things you needed when you saw him... Han Jisung entering a instrument store, probably to buy new strings for his guitar.

You were curious so you entered the store and pretended to look around to check the instruments they were selling. But you were actually stealing glances at Jisung, he's so popular around school and also so handsome, you can't help but be drawn to him.
