To my many obnoxious personalities

The beautiful port city of La Spezia. After leaving the orphanage, Monica, who served as a nurse on the battlefield for three years, is hired as a tutor by the wealthy Mallett family. On her first day in a strange city, Monica runs into a familiar face on the street. “… brush?" “Sorry, but I am not Sol.” I thought it was Sol, a soldier who took great care of me on the battlefield, but I was mistaken for the attitude of seeing him for the first time in my life. How come this man… Every time you meet, your name and personality change?! The only thing that's the same is a picture-like appearance and a light scar around the right eye. liar? identical twins? Or maybe he has multiple personalities?!
