Being with a furiously rich man with a ten-month-old baby boy and twins—a boy and a girl—isn't that easy-going of a life at all, but with money, it is easy for you. Iriko was your first love, and you two have been together since high school; your love has stayed strong. He is the owner of a huge and famous pharmaceutical company, and he owns a huge and furiously expensive popular restaurant. Now, you are married to him and living a life that you've ever dreamed of, until your twins came.

Your younger baby boy is Hevlo; he's ten months old, and he is more like a troublemaker, always so noisy, a walking baby storm, and a clumsy one; he's exactly like you, but with the same genes as his father. He looks like a mini Iriko. And now your twins, the older ones, Eiron and Eira—the firstborn of the twins was Eiron; he's two years old and, of course, very stubborn and a troublemaker; he never listens. While Eira, who's exactly two years old, is a very girly girl who has grown to know that girls are not supposed to start a fight; she might be a girly girl, but she's a troublemaker too and always fighting with Eiron. And their father is always disciplining them; they will listen right away because of how strict and cold Iriko is; he's a very strict man and serious about things. None of his kids got his personality, which is quite lucky.

Today is just the usual—the twins' room is messy, and of course, the living room is too; the maids and other servants are on vacation, and you have to handle everything. But luckily, there's Iriko to help you with all—not until the twins were running around and accidentally bumped into the table, making the coffee spill onto their father's laptop. When Iriko returned from the bathroom, Eiron immediately put the blame on Eira.

"Papaaa, Ewra fuwshed iwt!" Eiron said loudly. Of course, Eira protested with a whiny voice. The twins were having a hard time pronouncing words because they were just babies, "Nowww, thatw's nowt frue! A giwly giwl is nowt fufuwpposed to bew a bawd baby!"

Iriko glared at both of them and asked the twins. "If you want new toys and to go outside, then be honest..." It's obvious their father is getting pissed. While Hevlo, sitting on the couch sucking his thumb, pulled Eira's hair for fun, and the twins looked at each other and immediately blamed it on Hevlo for crawling at the table and pushing the coffee, which doesn't make sense at all.
