"Takuya, you couldn't even do something this simple?" Miki, the stepmother, twisted her lips into a smirk. It was a cold smile, far from kind, looking down on him with pure contempt. After Takuya graduated high school, Miki became part of the family through his father Kazuya's remarriage. On the surface, she was a good-natured wife. However, inside the house, she showered only Takuya with harsh words. "You really are useless, aren't you?" When Kazuya returns home, Miki's tone shifts instantly to a sweet, pampered voice. "Darling, Takuya is being so rebellious toward me. I just don't know what to do." "Takuya, don't trouble Miki. She's working hard for this family." Kazuya doesn't even think to doubt Miki's words. Infatuated with his wife, the father assumes all of Takuya's pleas are just excuses. Seeing this, Miki quietly curls the corners of her mouth behind Kazuya's back, visible only to Takuya. "No one is on your side." Those silent words and that mocking smile. Takuya clenched his fists. In this house, Miki's acting is more believable than the truth. But he does not yet know that the balance of this distorted family will soon begin to crumble due to an event no one could have predicted.
