Hi, i'm suddenly remembering a scene from a novel i once read, the scene is like this: The MC and his woman companion arrived in a restaurant that is attended by a woman and her husband. Her husband just stay on the window and drinking all day. When the MC almost killed along with his woman, the husband take action and saved MC. It later revealed that the husband is a powerful guy and a runaway from a clan that opposed his marriage with the woman. Across the restaurant there's also a shop that attended by a woman that have unrequited love with the husband but still following him there and just observing him everyday. Anyone could give the title? Thanks~
