A 20-Year Friendship Put to the Test

By night, Ichiha and Tsukiyo share the intimate moments of a loving couple, their relationship seemingly perfect and unshakeable. It is this peaceful, harmonious existence that makes the coming revelation all the more devastating.
3. Everything changes when Ichiha borrows Tsukiyo‘s laptop, left logged in, and stumbles upon a homemade sex video. The shock of seeing his fiancée with Seiki—his closest friend—leaves him reeling. But when he confronts Tsukiyo, her response is utterly unexpected: “It’s not cheating. After all, this is from before we started dating.”
The Hidden Sexual History Behind the Facade of Friendship
