Story Synopsis

I was suddenly hospitalized. For me, it was like an early winter vacation.

In the hospital, there was a girl the same age as I. Her name was Rika. She was selfish. Like she was a queen. But, her selfishness was inevitable...

From time to time, Rika becomes silent.

She just stares at Houdaiyama.

Though I'm beside her, she ignores me completely.

When will my hands reach her? When will I be able to bring her to the place she dreams of----?
