Ai Cheng Karen finally managed to shoo away her gossip-loving mother.
Kagura Hikaru fell silent for a moment, "....Your mom takes really good care of herself."
He had honestly thought she was Ai Cheng Karen's older sister or something of the sort.
Ai Cheng Karen forced a couple of awkward laughs, "Yeah, I guess so."
"....Let's get the guitar out," said Kagura Hikaru. "Let's practice a bit before your friend comes over. Did you practice with the textbook last night?"
"Yes, I did! I just got to climbing grids."
"? Climbing what grids?"
"Ah? Don't I have to practice that?"
"It's a skill that's completely useless, better to start practicing chords."
And so, they started practicing chord shapes.
Chords, simply put, are combinations of multiple strings being pressed at the same time, a technique that is often used during play; it's an inescapable part of practice for beginners.
