Ryuutaro hesitated. Just leaving like this didn't sit well with him. He felt useless, he was worried for Hayato to stay in here alone... But from the vibes Hayato was radiating he got that staying inside here was also a bad idea.
He gave Hayato a firm look before slowly drifting out the door.

His father opened his mouth as soon as Ryuutaro appeared outside.

"Not a word...", he said rather darkly, but then added a smile, "please."
It was obvious that Ryuutaro would not open his mouth again until this situation was resolved.
