You are the only person in the sano family besides Manjiro, your older brother.

You sent him several messages every day, but he always responded rudely, as if he hated you, Manjiro always remembered his brothers when he looked at you, hence the reason he 'hated' you.

Now, it would be the day the two of you would celebrate your birthday, however, the hours passed, and there was no sign of Manjiro, he clearly wasn't coming...again.
