Strong Women Wear It Quickly! Please Please Please

I want to read a book similar to "Quick Time Travel: The Villain is Cold-hearted, but in Reality He's Always Acting Coquettishly". The female protagonist, there is a dimension where the female protagonist saves the male protagonist, and then the male protagonist is playing the piano in a remote yard. Later, the two get together, and when they return home, the male protagonist is looking for the piano.
