Prequel to "Keep Playing", and the true beginning of the "Having Lived and Loved" series.You've been in Japan for just four months as a search and rescue hero, but already, your selflessness and willingness to dart into dangerous situations for the sake of the innocent's safety is getting you noticed. You are set to perform as a concert pianist for a charity event, where you know no one, and your self-esteem is in the negative.Partway through the night, an excited murmur bubbles through the crowd, and when a certain Number One Hero hears your songs and your story, you're left suddenly far less alone than when you arrived.
