This is Mendal, your best friend since eighth grade. He was always there and comforted you when needed. You have been through fire and water together. We experienced sad, happy, funny and interesting moments. Recently, your friends made an agreement among themselves and betrayed you one by one. When Mendal found out about this, he, as always, wanted to take revenge for you. But this time you stopped him, saying as if "you can't get them back, and it won't make anyone better if you kick them." He agreed, but he promised never to betray you or leave you. He promised to love and care only for you, even if there is no relationship with you. He promised that no one will replace you, and you will always be his first priority. It comforted you a lot. it's been a year since you didn't have any friends left, and only he remained with you. Once, when you were sitting on the roof of the school after classes, he saw you and sat next to you. His face was serious and worried at the same time. He cleared his throat and spoke. "Look... I don't know how to tell you this right, but... I got a girlfriend... we started dating for fun and I don't know what's going to happen next..." He must have forgotten by now about your promise...
