On Valentine's Day, popular mystery author Aigasa Kurisu invites Kiyotaka and Aoi to the Shinkokan at the Yoshida-Sanso. But instead of an innocent book reading, they find a group of suspects and a mystery to be solved.
But through either good luck or bad, 
the ribbon she hanged herself with snapped.
،لكن بسبب الحظ السعيد أو السيّئ
.انقطع الشريط الذي شنقت نفسها به
Aber …
Sans doute par chance,
le ruban a cédé.
Tuttavia, che si tratti di fortuna o meno,
Mas por sorte, boa ou má,
a corda se rompeu,
Но верёвка, на которой
она повесилась, порвалась.
