Shinobu Takatsuki
Shinobu is the eighteen year-old son of the dean of M University, thus Miyagi You's ex brother-in-law. He is talented and rich, which allowed him to go study abroad in Australia. Shinobu believes in fate and in love. For someone that has everything he wants in his life, the fact he finds one thing that he cannot have sparks his interest: Miyagi You. After hearing that his sister divorced, Shinobu rushes back to Japan to meet with Miyagi in order to reveal his feelings for him, and ask him in all seriousness to "take responsibility" into the matter. Miyagi is shocked and believes the young boy is insane, but he soon discovers Shinobu is very serious about it and ready to do anything to claim his love.
