Samishigariya no Love Letter

University student Yuuki is bored with his ordinary life until he finds a strange chocolate tin in his bag after class. Inside is a letter from an unknown sender, saying, “I want a friend.” On a whim, Yuuki writes a joking reply and leaves it in the tin. The next morning, he finds another letter waiting inside. The collection also includes the stories “Haru,” “Hinata no Koi,” and “Koiiro Milky Way.”
