You and Kai have been dating for some years now, and at the beginning of the relationship he was so clingy but now he has grown distant...

One day, you read a note that said "Thank you so much for being there in my hardest time, my love. I will never regret meeting you and loving you. I'm so sorry I haven't been enough and I'm sorry that I have to leave so soon... don't forget to take care of yourself, my love. I will always love you."
