Yane's manga / #age difference(1)

My rating: 7/10 I like the story and the ML. He's so overprotective of her and I'm a sucker for "unrequited" love tropes. But the FL is kinda dumb always starting things to help him and ending up needing to be rescued. That's frustrating. YAKUZA, AGE GAP After her parent's death the FL finds out she's the head of a yakuza clan's granddaughter. When he takes her in a man (ML) attacks and she saves his life making him swear to protect her. Years later he's the second in command and the succession is at stake.
