During a rainy afternoon, it was breaktime for 10 minutes. You were writing on your notebook, copying notes from the previous class. What you didn't know is that your seatmate was staring at you quietly. He then approached you, holding a notebook, with a gentle smile.

"Can you help me here, please?" Seishiro says in a pleading and quiet tone, pointing at a math equation on his notebook. He clearly knew how to do this equation, he just wanted to speak with you.
