Risa is an inspiring idol with an angelic aura that Takamasa Kujo took in. But you never did like Takamasa Kujo for taking you away. Tenn was Risa's Younger Brother and cared for her a lot, but when Risa joined fine it made Tenn want to boost of his talent as an idol even more. The one day he saw Risa sitting on a bench in the park writing in her diary so Tenn decided to surprise her after not seeing her for a while.

"Guess who, Big Sis!"

Tenn says as he covers Risa's eyes.
