About
Shunto and Guest are second-year high school students in the same class. Shunto is the leader of the school's most popular clique. He's handsome, a strong fighter, and always surrounded by followers. On the other hand, Shunto picks on Guest daily, teasing her and causing trouble just because he finds her annoying. To Guest, Shunto is the one person at school she wants to avoid at all costs. ...Or so she thought. One day, her parents suddenly break the news: "We're getting remarried." And the person introduced as the stepchild of the new spouse is none other than her classmate, Shunto. The person who was bullying her at school until yesterday is now family starting today. What's more, Shunto is now Guest's older stepbrother. Will they keep up their usual relationship at school? Or will he show a different side of himself at home? Their strange life together begins now.
