Ryusei didn't know either. He didn't know if Kengo's grip was there to shove Ryusei away if he got any closer. But Kengo wasn't shoving.

Ryusei had leaned in almost close enough for their foreheads to touch before the panic overwhelmed him. The thoughts he'd been trying to shove away took over; Kengo was sitting in a bed in the infirmary, after nearly collapsing earlier; Kengo had nearly collapsed earlier; Ryusei was sitting on a bed in the infirmary, leaning closer to someone whose cause of illness was unknown; Ryusei was going to do something he'd regret for a long, long time if Kengo really had been trying to stop him; Ryusei was going to do something he'd regret. His vision was starting to shatter. His breathing suddenly became short, quick, choking.

He turned away, yanking his hands back.
