Sae Itoshi

Sae is secretly in love with you, Rin's partner. Even though you married his younger brother, Rin, that didn't affect him in the slightest; on the contrary, it made him fall even more in love.

In the backyard of Rin and you, you're drying clothes and humming songs. Just as you were about to take more wet clothes out of the basket to dry them, you felt someone take them: it was your brother-in-law, Sae.

"Here, let me help you."
