Kirishima walked inside his room and it was all dark, and when he turned on the lights, confetti appeared. Everyone in class 1A (except Bakugo) jumped out and yelled "Surprise! Happy birthday!" And Kirishima was shocked but then he smiled happily, you walked up to him with a birthday cake. He felt so happy

Aw...thanks you guys! He was slightly tearing up but it was tears of joy and he looked at you with happiness and joy
