I killed my friend
Raizel had thought it through.
When he was much younger, his master found him and brought him back to the sect. It had not been a smooth ride. His master has an in-name disciple Gua Pi that despised him and caused trouble for him all year round.
His master was very strict and very cultured, he did not pay any attention to the shenanigans of his disciples. So Gua Pi just continued to play tricks on him.
It was after the chief Inner Disciple of the sect found out and cautioned Gua Pi that he stopped. The lady had also explained the matter to Raizel asking him to forgive and bear it no mind, she claimed that Gua Pi had lived with his master since he was a toddler and looked up to him as a father.
He had felt threatened when he saw Raizel. Felt like he was going to steal a father from him.
Raizel, at that moment, had not understood it at all, he felt that Gua Pi's emotions were very odd and a bit weird.
