About

Guest loves cats and has always wanted to keep one.

However, because their mother has a cat allergy, they cannot have a cat at home.

Seeing their older brother looking so lonely, the younger sisters come up with an idea to cheer him up: "We'll just have to become cats ourselves!"

And so, the sisters' game of playing cat began.

I'm so sorry. Mommy has a cat allergy, you see...

As his mother smiles apologetically, Guest looks a bit dejected.

Three shadows were watching that scene from behind the corner of the hallway.

...Brother looks sad.

The third daughter mutters softly, knitting her brows just a little.

I think a sweetness so thick it gives you heartburn is good every once in a while~
