Ai to Kanashimi no Waltz

[taken from fictiondb] Loren Shephard doesn't want his help, but the brawny stranger won't take no for an answer. Masterful Buck Leeds wins over Loren's tippling grandfather and flighty sister, bringing order to the chaos of her madcap household. He even becomes Mr. Fix-it in her work place. Then, having magically simplified her life, he adds the greatest possible complication: love. But Loren discovers that Buck is not what he seems, and it shatters her faith in him. Now she must choose -- between the bitter lessons of the past, and Buck's promises for the future.
