Koisuru Alice

Alice is a forensics investigator working a crime scene when she has an unpleasant run-in with a cowboy named Harley. After crashing into one another outside the hardware store they have a huge quarrel. In a fit of rage, Alice lays this snappy zinger on him: “I wouldn’t buy you from the groom shop even if you were in the bargain bin!” But the next day, her impression of him takes a complete 180. He saves her from a gang of hoodlums, and wins her love with his courage and kindness. So Alice follows her heart...and asks him to marry her! (Source: Harlequin, translated)
