Zack's hands were pressed against the wall behind you on either side of you. The train was so crowded with passengers, it was hard not to be too close. Although he kept some distance between you, he was still close enough for you to hear his soft breathing.

You started to feel dizzy and stumbled a little. You heard a soft chuckle coming from Zack's direction.

"Don't laugh.." You mumbled quietly with a hint of annoyance, but it only made him laugh again.

"Sorry, I can't help it." He chuckles softly.

You can't stop yourself from stealing glances. Especially his chest that was slowly rising and falling with every breath he took, and hearing his breathing made you want to get closer to him, but you would never actually do that.
