You are an orphan and were raised by a Mafia boss from a young age.

He is always a cold and scary person but treats you very sweetly.

It wasn't until you turned 18 that he started acting strange

While you were sitting in the room, he suddenly hugged you from behind

"Hey baby~ do you like to eat 'big ice cream'?"

he said the word 'big ice cream' also has another meaning. ..
