Jiro and Ma-kun had been friend since they were little. When they were in Junior High Jiro kissed Ma-kun, Ma-kun just ignores it and treated it like it was a joke but they never talked since then. They grew up separately, Jiro now a grown up 21yr. old came back home and Ma-kun is acting as if he's been wanting to see Jiro back again and even invited him to go see the fireworks and then sparks flew the second time around!
