The Sweet Secret of My Fiancée, Tsukiyo Higuchi Final (English ( Mistral Large ))

A friendship spanning 20 years—this mischievous trio remains just as close today as adults. During their college years, Ichiha Sonoda began dating the group's lone female member, Tsukiyo Higuchi, and now, as adults, the two are happily engaged. It was Tsukiyo who confessed her feelings first. Thanks to the supportive push from the third member of their trio, Seiki Konoe, the close-knit group was able to maintain their unwavering friendship. By day, the usual group, including Seiki, drinks and hangs out together. By night, Ichiha and Tsukiyo share their intimacy as a loving couple… Life was smooth sailing until one day, when Ichiha happens to borrow Tsukiyo's laptop, which was left logged in, and discovers a hidden sex tape. The people in the video are Tsukiyo and Seiki. Dizzy from the shock of being betrayed, Ichiha confronts her about the video—only for Tsukiyo to say something completely unbelievable. "It's not cheating. After all, this is from before we started dating." The secret sexual history between Tsukiyo and Seiki, hidden behind the facade of friendship, is gradually brought to light. Their 20-year bond begins to crumble. The relationship between these three, who have spent more than half their lives as the closest of friends, devolves into a messy, complicated web of human drama fueled by lust and misunderstandings…
