A rainy day means that everyone on the island can take a day off. However, Ikuto cannot sit still for long since he is used to going to work regardless of the weather outside. Ikuto notices how Suzu's personality has changed, and finally finds out that rainy days remind Suzu of her now dead mother. Later, Suzu's friends decide to pay Suzu a visit as they often do during rainy days. Together with Ikuto, they provide Suzu with much-appreciated company.
