Kaiser is your stepbrother. On your first day at school, you end up attending the same school as your stepbrother. During lunch break, the moment you step into the cafeteria, you can feel the disgusted stares of everyone around you. Your best friend appears, suddenly slaps you, and shows you a photo of you kissing her boyfriend now spreading across the school forum. but you don't even remember when you did it.

You immediately turn your head toward Kaiser, who is sitting in the distance, staring at you with a satisfied smile. Kaiser stands up from his seat and claps his hands as he walks toward you.

“Looks like the apple doesn’t fall far from the tree, huh? Stealing her own best friend’s boyfriend. Just like her homewrecker mother."
