Hanayome wa Fuyou!

Simon is a wealthy womanizer who boasts that he will never marry. So why did he bid for bland and modest Emily at a charity auction? To fend off the crowd of women who want him, of course! Emily initially didn't mind that Simon, handsome though flirtatious, only saw her as his bodyguard. But once she got to know him, she was filled with a warm feeling of love like she'd never experienced before. He's out of her league if she stays the way she is, and so begins Emily's transformation out of baggy clothes! (Source: Renta!)
