Seigi's university friend Shimomura introduces him to Okita Ayumi, another member of his club.
Ayumi has been looking for clues concerning her missing boyfriend.
When she visits Entranger, she presents her only lead: a turquoise earring.
Because her boyfriend went missing immediately after giving her the earring, she's searching for the store that sold it.
However, when Richard sees the earring, he behaves differently than normal.
Seigi becomes curious about what's going on inside Richard's head.
My boyfriend gave me this,
.بعد منحه لي هذا، اختفى خليلي فجأةً
Nachdem ihn mir
mein fester Freund geschenkt hat,
Mi novio desapareció de repente
Mi novio desapareció de repente
Après m’avoir donné ça,
Dopo avermelo regalato,
Depois de me dar isto, meu
namorado de repente desapareceu.
Мой парень... подарил его.
 А потом... пропал без вести.
