[1] After his partner Yuri leaves him, Ryo spends a lot of time depressed, not knowing where he has gone.
Ryo learns that he has his own doppelgänger named Ryu, who is coincidentally a skilled magician, in Hokkaido.

She was so troubled by Ryo's death that her aunt brought her to Tokyo where she created a new identity for herself, calling herself Yuri.
Her emotional health was too fragile to stand the shock of finding out that who she wanted to believe was Ryu was actually Ryo.
Ryo breaks her out by performing a magic trick at her hospital and they spend a long time together and have an in-depth exchange about identity.
