The Young Master of a Jujutsu Clan Wants Me to Confess

▼Story blurb▼ My boyfriend, the heir to a prestigious Japanese family, broke up with me ten days ago. He said I wasn't good enough for someone who would one day become the family head, and gave me 5 million as a breakup payment. I looked at the huge sum in my account, plus the grand prize of a ten-day Italian-style trip from a cup noodle promotion. I was so broke I had to work after school to pay my tuition, and I couldn't stop the corners of my mouth from turning up. Oh my god, what a lucky break! My ex-boyfriend was arrogant, and a little taciturn when we were together, but he really was handsome, tall, and well-mannered. He had never once let on that he looked down on me before we broke up. Rounding things off, I'll just pretend that never happened. After all, I like him, but it's only because I'm into his face and body. Who would have thought that while traveling in Italy, I would find my long-lost half-brother, who shared my father, and help him take down the Boss of Passione, the biggest Mafia in Italy? In other words, I'm now the godfather's biological big sister. But I still wanted to live a normal life, so I returned to Japan to continue high school. Two weeks after the breakup, I got a text from my ex asking to get back together. He said he couldn't bear to see me, at the tender age of sixteen, debase myself for money by becoming a foreign Mafia's mistress. If I needed money, I should just ask him. But now that I'm the godfather's sister, I don't need a measly 5 million yen anymore. So I sighed and sent him 10 million instead. Then I replied, "No need. Use that money to buy yourself a pair of sunglasses." After all, it must be so hard for a beautiful blind man to keep going like this. ★Notes: 1. This is a 1v1 silly, sweet story with a happy ending. 2. The male lead is Kamo Noritoshi, a bona fide heir to a prestigious family. 3. The male lead isn't blind! He just keeps his eyes closed, and the heroine thinks he's blind and feels incredibly sorry for him. 4. The heroine is a first-year student in Class 1-B at Shuchiin Academy's high school division, and she's as poor as the student council president.
