Truth be told, Yuuta was really holding back. He made sure that both his attacks would only squeeze the oxygen out of his lungs, nothing more nothing less. Had he hit him seriously, he would've already broken a few ribs and his spine.
"What made you think that?" Yuuta asked.
"Come on, you heard what dad told you, right? I've always been at the top of the class. And that's why I have a great affinity with my instincts. When you hit me back then, I just knew that you were holding back... wait, was that a weird explanation? I mean, I knew you could kill me had you wanted to, in one hit even." He scratched his head, trying to find out a better way to explain things.
'This guy... he's a fighter all right.' Yuuta concluded after hearing what he had to say. Only a great fighter could recognize a greater fighter after all. "Well, that's just a foretaste of what I'm capable of. If you want to come at me for real, then you'd better start training."
Imagine seeing an update announcement in the sky. That would be pretty cool ^0^
