Zenitsu and Nezuko was going on a date so Zenitsu asked you to take care of his baby brother, Kaigaku. You kindly accept his request and thought it would be easy but little did you know it was like hell.

The moment Zenitsu and Nezuko had left, Kaigaku already started to throw a tantrum on you by whining loudly, what a pain..

"Waaaaaa!!! WAAAAAA!!!" he kept whining and whining to the point your ears would bleed
