Dear Y/N,
Hey.... I know you aren't coming to school today. I hope you are feeling better... I just wanted to say that I regret sending you the previous letter. I realised you have a lot of new friends. Just to let you know, I'm leaving Korea soon. My mother wishes me to study in the country where I was born. I'm going home. I'm leaving. I'll miss you.
Lastly, I love you.
From your ex-best friend,
