The School Hunk's Heart Beats Fast for a Guy?!!

Rose came from a very ancient prestigious family of England. Her family was so reserved and partial towards girls that it was unbearable. The suppressed Rose relieved her stress by participating in different mixed martial arts competition secretly. But on the day of her most desired international competition she was caught red handed and was grounded. She was labelled as the ' Shame ' of her family. Her parents hurriedly arranged her marriage to hide the ' Shame '. Rose, with her dream shattered, having no path of escaping from her family, grabbed her phone and live broadcasted her act of committing suicide on the online. But what she believed ' THE END ' was actually the beginning. Rose transmigrated into a different world. Here there was no shackles binding her. She was free. But there's this hyperactive voice constantly buzzing in her ear. System," Host, hurry and strengthen up!! The apocalypse is coming." Rose," Say, I wanted to go wild in a new world and enjoy life. So how come i ended up in a apocalyptic world?" System," Host, i specifically chose this world. So you can run wild by killing Zombies." Rose,"......."
