"When I think about you, Yamada, I lose sight of everything around me."
It'd be interesting to see him deploy that line regarding his injury, considering that *Yamada's* big injury (getting smacked by the basketball in chapter 14) also happened because she spaced out staring at/thinking about Ichi and wasn't paying attention to what was going on around her.
tbh a drama of guilt or misunderstanding is probably the means for either one of them to start confessing. if this is grounds for a confession scene im all for it.
