What happen if our tuna-fish have a greatest secret that no one knows exept his mother , father , Reborn and Vongola nono

When you turn 16, your dad and I decide to engages you with your dad's boss's grandson. What?! You gotta be kidding with me, right mom? I'm not joking, honey. We already decide before you born. I'm not ready to be someone else bride. What if he does not accept me who really I am? XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Where the wedding be held, Reborn? Vongola Church, near the Vongola Mansion in Sicily, Italy. WHAT????! Oh I forget! Nono invites your classmates to your wedding day. So it's not a SCHOOL TRIP after all?! You've lying..... She is unconscious on the floor. So many surprised....

Sawada Tsunayuki, a supposedly 'normal' highschool student but with her father working in Vongola Corporation with a high role but not high as the boss that has a dark secret and that is being involved in the mafia but not just involved as it's the strongest mafia in the world. How could Sawada Tsunayuki be an normal student if she has that kind of father and that she always meets weird people but rather good looking and is a magnet for trouble? How could she be normal when she's famous to the whole world and that she has a brother that is an idol that she doesn't even know? Yup, Definitely 'normal'. ------------------------------------------- Katekyo Hitman Reborn is not mine and some of the plot.
