I forgot the name of this fairly recent Chinese manga where a martial artist ran away from his martial art life. It seems he was a vagabond until he found himself in I think Japan where he met a woman who is having trouble with a local gang to keep her restaurant open. It was love at first strike for him one look at her and helped her. He became a live in worker/protector at for her and her restaurant. One by one he subdued one gang at a time to the point they fear him so much that they are willing to do anything he ask. Last time I checked about 15 chapters have been scanlated so far. It was very entertaining (comedy).
