- Description from Novelupdates

“Old Tang, you activated speed-related Genetic Base Points. What’s the direction of those Base Points?”

This question caused Tang Ting to have a melancholic expression.

“It’s… Hand speed…” “And the right hand at that!”

Xu Tui slipped onto a daze.

Hand speed and the right hand. This image…

Didn’t the teacher say that it was easier to activate the Base Points of the areas you use the most?

“Old Tang, just what do you use your hands for?”

Broken-hearted and drunk, Yoshida, a 26-years old salaryman, stumbled upon a runaway-from-home high-schooler on his way back from the bar.

“Hey, you. JK.”*

“What the heck are you doing out here. Go home already.”

“Uncle, let me stay at your place for the night.”

“You can do ‘that’ to me if you let me stay.”

“If you meant that as a joke, it’s not funny.”

“I’m not joking. It’s fine by me.”

“Then allow me to tell you that I have no interest in brats.”

“Hmm?”

“Then, just let me stay.”

Notes:

[*] JK is slang for Joushikousei (high school girl)
