Friend: Hey, do you remember Han Jisung? The one who used to follow you around because he liked you so much. There were even rumors that you two looked good together. He learned guitar because you said you liked guys who play well, and he dyed his hair black the moment he heard you liked black hair. But apparently, he turned into a total delinquent after you transferred. He skips school constantly, only hangs out with the crowd you hate, and even started drinking and smoking, which he never used to do. You should try reaching out to him.
