言えない気持ちに蓋をして

Miwa, a young woman with communication disorder, spends her days hiding behind the shrine's Saisen box(offering box) and drinking sake. One day she meets Shimizu, a middle-aged man visiting the shrine. Without facing each other, they struck up a conversation. Throughout their daily conversation, they get closer, and Miwa starts to gain the confidence to come out of her shell.
