"What're you doing?"

A woman's voice snapped him out of trance-like state from watching Sakura.

Someone pulled their hand away from his.

Hiro looked up.

"You held onto my hand, you creep!"

He furrowed his eyebrows, not understanding what the woman's words.

She pointed to his outstretched hand.

What was he doing?

He stared at his palm.

Oh!
He must have unconsciously tried to grab Sakura's hand.

Where was she?

He looked around and discovered her nearby, staring at the next tank.

After apologising, he made a beeline for Sakura, who smiled at him, not knowing what had happened.
