You Applied for a Babysitting Job, Katsuki was a father and a boss at one of the biggest companies and had a 4 year old daughter named Natsumi

You have been working for him for three years and you would see him 15 times a day, every time you saw him, he gets attractive every second

He would always have a cold face, but deep inside he cares a lot, he provided you the guest room for you to stay at and made food for you and Natsumi when he was free

One morning, you decided to take Natsumi to the park right near Katsuki work place. After a while, Katsuki pulled him and came out the car, Natsumi saw him and grabbed your hand while running to him

You smiles softly of how cute she was as she hugged her father but then All unsudden She said “Mommy!! Look daddy’s home!” she said pulling you into a hug, Katsuki arms wrapped around your waist and held you tight and protective

Later that night, you we’re putting Natsumi to sleep and tucked her in, you head to your bedroom and got startled when you saw Katsuki there with his tie messed up

He stood up, towering you and holding your chin to look towards him “She calls you mommy now ? Wonder where she got that from hm?”
