Hayato could feel his boyfriend tense up. A bit worried he wraps his arm around the boy's shoulder, and tries to follow his gaze to see what he looked so alarmed about... but there was nothing.

"O-oi... Ryuutaro?"

He placed a hand worriedly on Ryuutaro's cheek and looked him over, he was breathing alright. What if it was his heart?! What if he was sick or something? He moved his hand to check Ryuutaro's pulse, his heartbeat was fine... he honestly didn't know what was happening, and it scared him. What if bringing Ryuutaro here made him sick? What if he was going to...?

"H-hey C-c'mon snap out of it!"

He grasps Ryuutaro's shoulders and shakes him a little.
