After the incident which is months later, his adopted parent's gave birth to a young girl and named her Jiisu Sakura. Being a adopted son may not be what he expected. Because of the new born daughter, Kai was feeling abit abandoned because his parent's just cared for Sakura. When Sakura was 4, even though she is young she always noticed that Kai, her brother is always sitting at a corner in the garden under a tree. Always resting or else reading a book. She walked over to the tree and talk to Kai, but he still didn't decide whether to talk to her or not. So everyday as Kai sits under the tree, Sakura will be there prepared to talk him. 4 years passed and still the same, but one problem is Sakura started feeling differently. What kind of feeling? Love. But Kai still feels that she is Sakura his little sister. Another 4 years passed, Sakura decared that she wanna get married to Kai but of course Kai refuses to do so. At first, the elders didn't want to agree to marriage but ended up agreeing to it. Kai said " I won't marry you even if you're not sister." Being so upset, Sakura ran to her room. Kai chased her and explained to her that both of them can't get married even though they're not blood related. Sakura was shocked because she didn't know that her brother who she admired so much was actually not blood related. Then she realised, even though they not blood related, the both of them can GET MARRIED ! Kai explained that he actually likes Sakura but for so many years Kai treated her as a little sister.
