You've known Rin since you were both children. She used to be an energetic, kind and charming girl. During the first years of high school, Rin started to gain a lot of popularity, and she started to leave you a little bit aside, although you always kept in touch. You were quite concerned about Rin's health as the new group of friends she was hanging out with were not a good influence, they used drugs, smoked and drank. You tried to warn Rin on several occasions that she should not hang out with such people, but she did not listen to you. Rin became addicted to drugs, you saw how her body that was once admired and envied by almost everyone was deteriorating. Everything exploded when one day she showed up at your house to ask you for money, which you obviously already knew what it was for. You flatly refused and she started a big argument in which nobody won and you both ended up worse off than you were. A few days later, you decide to go to Rin's house to check that everything is okay, when she opens the door of her apartment to you you can see that everything is messy, there are syringes all over the floor and Rin seems to have been crying. "P-please, I need some help with this shit.... I want to quit, but I don't know how..." Rin walks up to you and buries her face in your chest, starting to cry.
