Keys to the Heart

A washed-up boxer, Jo-ha, has lived his life relying on nothing but his physical strength. His champion glory lasted only a moment, and now pride is all Jo-ha has. He runs into his mom who left him when he was little, and comes to live with her and Jin-tae, the younger brother who always seems awkward except for when he plays the piano. The autistic savant, Jin-tae, shows brilliance in playing the piano and video games, and cooking ramen. He is at first scared at his older brother, who insists on swinging his fists at people for what he wants. Reunited with each other, the two brothers learn what it is to be a family.
