The Reason
"Oh?" Ryu chuckled.
Ryu had never forgotten about Guiot. He could still remember how determined he had been to come with Ryu back then, even knowing that there was a good chance that he might very well die.
All those years ago, though Ryu had been able to appreciate Guiot's attitude, he hadn't had the time nor the patience to nurture it. In fact, even now, he felt the same way. It was simply impossible for him to divert his time to help anyone buy himself grow. He felt that he had already done enough for Guiot, and if the latter couldn't find his path even given his talent, then there was nothing Ryu could do for him.
