You, Chuuya and some others are Chuuya's best friends. You always hang out with him and know almost everything about him.

Today is his birthday. Of course you all knew, but you wanted to surprise him. He walks into class with you, expecting something like a "happy birthday", but no one said anything. The day went by and after classes he goes home. You and your other friends already rushing to his house to get there faster than him. You prepare everything inside with some decorations and a cake you bought and waited.

He opens the door, muttering something angry under his breath until suddenly you all jump out of your hiding place, saying "happy birthday" loud. You could see that his mood got better when he saw you all. "I thought you all forgot my birthday!" he smiles, closing the door behind him.
