"Are you perhaps using 'you' or 'that bastard' instead of 'you'?" Yu Jung-ak said as he walked, looking at Yui.
"It's similar."
"Who is it?"
"I don't really..."
"He looked like an athlete."
"An athlete?"
"His arms are long. They seem to almost reach his knees. Plus, there are dark bruises on his knuckles. That happens when you hit the sandbag a lot without wrapping. Right, Rumsak?"
"That's usually the case."
"A boxer?"
"Don't know. But sometimes it happens even with wrapping."
Rumsak Noi said. Yu Jung-ak was walking again, following Satomi.
"In what cases?"
"It happens when the punching power is strong. But it's not just because of strong punching power. The skin on the knuckles also needs to be weak."
"Don't you get calluses if you hit the bag for a long time?"
"Even with calluses, some people end up like that."
