Well his sister might try to pester him that Hayato and him have similarities but being the lonewolf he is he will just dismiss what she said as nonsense and walk away without saying a word. She would definitely say that he should try to befriend Hayato since he also has a father who wanted to push Shinrei but his father wanted him to be the very best showing really no attention toward his sister at all. All eyes were on him which infuriated him beyond belief. Even though she would say that to him, Shinrei isn't one known to get close to people he doesn't know. In fact, he hates it when people try to befriend him, because he wants to depend on no one but himself.
