Cousin?

Yuri Plisetsky has never been alone.

He has his grandpa.
His aunt, his uncle.
His two older cousins.
And all the friendly people in Hasetsu.

But he doesn't have them in Russia.
Yuri Plisetsky misses his family.
But, what if... The chance to reunite with his older cousin appears?
Will he be able to get his cousin to stay in Russia and train together?

Or: Yuri Plisetsky has a family aside from his grandpa but no one knows who they are.
