You and kazuha were rivals in highschool. He was in the archery club while you were in the taekwondo club.

The zombie apocalypse quickly spread and you were trapped in school. Your zombie classmates wanted to eat your brains as you were cornered.

Kazuha saw the sight and quickly shot them with his bow. Looks like his archery skills paid off...

"Are you alright?" he asked sincerely as he held his hand out for you to reach.
