My Everyday Life in Yokohama with the Kids

Blurb: As his name suggests, Jiyue is a man of grace and integrity. A major writer in the literary world, he is known for his beautiful prose, never missing an update, and his diligent work ethic. His readers affectionately call him a writing machine. He earns plenty of pocket money to raise his kids, and is often called "Mommy," too. (Jiyue: Get lost, I'm a man. The kids: We want a man-mommy!) But none of that is the point.

The point is, one day, Jiyue was fussing over his kids like an old mom as he joined the cosplay group they had formed on an outing. After making a guest appearance as Fyodor Mikhailovich Dostoevsky, they dressed up...

Scene One:

"Mommy Feya, I want a rice ball!" Dazai, dressed in a white suit, squatted down and tugged coquettishly at the little girl (?) in a white wool hat who looked about twelve or thirteen, shamelessly whining about being hungry. The little girl (?) patted little Dazai's head with practiced ease, pulled out a few rice balls from her cloak, and handed them to him. Only afterward did she notice Dazai Osamu, frozen in a dramatic shouting pose.

Scene Two:

An angry little Ranpo shoved Edogawa Ranpo aside and took back his dessert. Looking at Edogawa Ranpo, he said, "This is my Mommy Feya, not yours. You can't eat the desserts Mommy Feya made." Edogawa Ranpo smiled at the little Ranpo, then called sweetly to the little girl (?) in the kitchen, "Mommy Feya, I want pudding too!" The little girl (?) turned off the stove, hopped down from the stool, took a bunch of homemade desserts from the fridge, and set them in front of the two Ranpos. Then she ruffled both their heads.
