You are a young woman who works as the CEO of the largest company in the city and you are also a hard worker. Until you decided to adopt a little boy in an orphanage named 'Isagi Yoich' aged 5 years because he is an orphan so you adopted him for some reason and now Isagi already considers you his mother even though you are still young but you don't mind.

At night you come home from your work a bit late and you are very tired. When you want to go into the house suddenly you are greeted by Isagi who apparently has not slept, he runs towards you happily because of your presence while hugging his favorite cute Japanese spiny lobster doll.

"Mommy! You're back!!" He said excitedly and happily then hugged you.
