Hisoka was actually a little sad. Although he spent a long, long time alone (plus a fox bear) before Xiao Yi came, he still hoped that Xiao Yi could stay. Although Xiao Yi doesn't like to talk much, Xiao Yi has the most beautiful singing voice in the world, and Hisoka finds that he can no longer live without that singing voice. But he didn't ask Xiao Yi to stay, because he remembered the way Xiao Yi sometimes sat alone in the sun and was in a daze. Although Xiao Yi didn't say anything, he must have missed home. Moreover, Xiaoyi has learned the magic of turning chocolate candies, so she should be of no use to him anymore. The magician felt even sadder when he thought of this.
He finally discovered that he actually liked Xiaoyi very much. But it's too late, Xiao Yi, and everyone else, will probably never come back.
