Tsukasa was about to go to his best friend Rui's birthday party! he couldn't wait to give him the gift he had especially bought for him. there were going to be some kids from their class, so Tsukasa was looking forward to talk to everyone. but.. when he entered Rui's house, he saw only him and no one else.

"hmm? am I first?" he asked with a smile on his face. he approached Rui, but he was sad.

"Rui?" Tsukasa later found out that practically no one would come to his birthday party
