There is a grave car accident witnessed firstly by X. X is a young and unpopular university student. Noticing that the car belongs to the most famous student of the university, X rushes out to look at what happened. The driver is dead and X steals his bracelet as a token before running away after hearing the ambulance coming.
The next day, X goes to school and we see his everyday life. We see he is getting bullied and/or ignored by the other students.
At the en of the day, he wishes out loud that he could be like (the guy in the accident) and be popular. He puts on the stolen bracelet.
The following day, people start acting strangely towards him. They are noticeably nicer. A girl on which X has had a crush on forever start talking with him, and being flirty. Whatever X says, people react hysterically.
At night, X is visited by a the ghost of the dead guy and he ask if he enjoys his celebrity life.
The day after, X starts becoming overwhelmed by how people react to him. They are harassing and almost downward dangerous to him.
At night the ghost comes back and tells him that the bracelet is cursed: it looks just like all the popular lucky bracelet that youths are wearing nowadays, but it is much more powerful. It will make the wearer become instantly popular, but it will also create such an aura around that person that people may eventually kill him by becoming too obsessed.
X weight the pros and cons of the new bracelet and finally decides to get rid of it because being popular is not worth dying for. (or something along those lines)
