Roki was waking up from a nap and he was in a mansion and he was looking out of his window alone in his room and he was hoping that he can find any answers on his mother for five months after it happens there was something that he couldn't get out of his mind and that was his mother didn't want him to find her but it was something that was behind his mother answers and then his brother.
Yoki appears out of nowhere and there was nothing that Yoki could have to say to change the situation but only that he didn't have the same answers as his brother Roki did and he just kept his own thoughts to himself.
