At the Calvin family home, Raymond and Richard took turns looking after their sick youngest sister. They wondered how all of a sudden, their sister got ill when she came home from school. Little Harmonie has been sleeping until now.
As soon as the twins finished their schoolwork, the two of them went into their sister's room to accompany the sick Harmonie.
Raymond was studying his school lesson while Richard was fiddling with his father's laptop he had brought from his father's room.
Born as the son of a genius unconquerable hacker, the twins inherited their father's abilities. However, Raymond was not fond of dealing with such complex programs. He was more interested in the regular general stuff like most other kids.
