I Will Protect You for the Rest of My Life

Have you ever wanted to go back in time? Will you take the same journey again, or will you make a new choice so that you have no regrets? How did you fantasize about it in your youth? The protagonist returns to ten years ago, and everything is still so familiar. Will people from the past still miss it? Should I leave no regrets, or start over and relive the beautiful love.
