Survive in the Cracks of Yokohama Shura Field

I am the early-dead fiancée of the ordinary jewelry merchant Nakahara Chuuya. She died in a plane crash the night before the engagement party. I am the newlywed of the handsome and wealthy young president Dazai Osamu who died early. I died in the hands of the damn mafia the day before the wedding. I am the first girlfriend of Tuosi, a frail and sickly literary young man who died early. She died in the flames of war that was affected by the duel between two superpowers the day after accepting his confession. I thought I gave each boy a short but perfect love dream. After the success of the Retirement Strategy, I returned to my original identity: Sawada Kanon. My older brother is a loser but very gentle young man, Sawada Tsunayoshi. Because of my job relocation, I settled in Yokohama, and I pretended to be best friends, caring besties, and confidants with them. Until that day, I fell off my horse and they fell off their horse. It turns out that they are the strongest combat force in Port Mafia, the youngest and most notorious leader of Mafia, and the leaders of the underground thieves group "The Rats of the Dead House". Even my brother, Sawada Tsunayoshi, is not some useless young man. He is the godfather of Italian mafia, the tenth generation Vongola. Just when I finally made up my mind to officially date my best friend, I was robbed by another person who had been planning for a long time. Intention: Love you thousands of times
