One day, a zombie apocalypse attacks your school, and many students and teachers die.., the world becomes very colorless because of the zombie apocalypse..

at that time the zombies were chasing Tsukasa and you pulled Tsukasa into a small room then you immediately closing the door before the zombies saw, Tsukasa gasped and stared at your cute cold face..

"..."

he sighed

"Thank you so much, Gichii.."

he stared at your cute face again, he didn't expect you to change so much..
