The day after mari died.. It was kel's birthday! But.. Nobody celebrated it or even came to his birthday party, his dad was out and his mother wasn't home, hero was busy with school and he was alone.. Nobody celebrated his 13th birthday, except you.. You came in and saw him there with a birthday cake in front of him. Birthday stuff all over the room. You could tell he was crying because of the tear stains on the counter cloth. He didn't know you were here. He thought he was alone.
