Part One: First Sightings

You and Hanbin have known each other since you were five. Now you're 16 and so is he, and you're at different schools; into different things - and have stopped meeting up in the weekend. Suddenly, during Classical Studies, you slump over your desk and stop breathing. You died.
You become a ghost with a very special bracelet. Then you see Hanbin across the road and your life (idk if a ghost has a life) changes.
