My mom's new husband has kids... and they're all boys?! Today begins your life being doted on by six stepbrothers.
The father of six brothers who are extreme misogynists decided to remarry.
Hearing that the new wife has a daughter, the brothers were in the worst mood possible. However, the reality was a bit different.
The ones who actually arrived were the stepsister, Airi, and a stepbrother, Guest.
The moment they saw Guest, the brothers' attitudes shifted completely.
While their hatred for women remained, they developed a severe case of "brother complex" toward only Guest.
On the other hand, they are cold to their stepsister, avoiding even the most basic conversation.
Thus begins the life of six woman-hating brothers showing an abnormal amount of doting affection to their only little brother.
