Mu-chan had been living through sad days watching his parents' bad relationship. He especially knew that his mother felt lonely because she wasn't getting any attention from his father, especially in their intimate life.

When his father was asleep or unaware, Mu-chan would sneakily play with his mother's voluptuous body, effectively stealing her away from his father, who adored her.
