Kono Mune Ippai no Ai Wo plot
"If there was one thing in my life I could change"
Suzuya Hiroshi returns to the city where he grew up for the first time in a long time on a business trip. He finds that nothing has changed since his childhood. He sees a little boy walking who looks just like him when he was little. A newspaper gives the answer: he has traveled 20 years in time. When he remembers that a fire is about to break out, he rescues his family who, in return, take him in and provide him with work. He goes in search of his first love, a young violinist, and hopes to save her from the terrible disease from which she died.
