One rainy afternoon--
Two boys, Satoru and Mio live together in an apartment. In bed, after caressing each other, they talk together about their woes during the dull period after sex.
In the middle of one of these conversations, Satoru reveals he's been looking for a new partner on the internet. He's been trying to deny these feelings, but Satoru feels unsatisfied.
