Mako was 18 when she became pregnant with her boyfriend's child. However, the boyfriend disappeared without a trace. Mako decided to become a single mother and gave birth to Kyota. Kyota is interested in art and after graduating from ● School, he apprenticed under a potter, living there while training. One day, at 20 years old, Kyota was told by his master to repay his mother's kindness, so he took time off and returned home, inviting Mako on a hot spring trip.
