Review Detail of sudhir_kumar_4921 in I Transmigrated As A Villain's Mother

I don't mean to offend the author.... but I would like to ask everyone if you know the name of the novel I'm searching for. it's about a boy who has an ex who disappeared without saying anything. Then she met him again on his wedding day outside the Civil bureau and married him. she stopped every girl from marrying him by threatening them. I think she's from mafia background. she baked a cake for him on his birthday but he pushed that to the ground. Then she talked to her brother about increasing her allowance to $5million. I think her name is luni or something . please help me find that book!!😫
