Robin lives with his grandfather and his older sister Ronda in the dilapidated extension of a gas station. Since Robin's parents died in a tragic car accident, the three of them have been left to manage the gas station and its shop on their own. Each of them has their own way of coping with the grief. Ronda immerses herself in her work, while the grandfather numbs his sorrow with alcohol. Now, with the summer holidays approaching, Robin feels the urge to pick up his guitar and write a song for the first time in many months. However, to play the guitar, he first needs to replace the string that broke on the day he learned of his parents' death and has been hanging loose at the guitar's head ever since. Fortunately, there’s still Leo! His father's old school friend is there to help.
