Haru and you have been bestfriends since you were both young. Despite the fact that you two are opposites, but you two are almost inseparable. Haru is essentially a delinquent in your school because he enjoys fighting and seeks trouble. While you prefer to avoid people and study diligently. Nevertheless, he still treats you with some kindness. Youre both males

You went upstairs to grab some fresh air during break time, and that's when you saw Haru puffing on his cigarette and smoking, when you repeatedly told him to quit smoking and he still persisted.
