My Sister-in-Law is My Childhood Crush

When Yuki returns to his hometown after years living in Tokyo—the place steeped in bittersweet memories—his gaze immediately locks onto Shizuka: his childhood crush. Growing up inseparable from Shizuka because she was an only child and older sister figure to him in their community life. While she happily accepted their sibling dynamic with everyone else seeing them as sisters-in-arms (or rather sisters!), Yuki secretly yearned for more; he wanted to be her man! But destiny had a different plan; Shizuka fell deeply for Yuki's older brother and was headed toward marriage. Driven by a need to erase those precious memories entirely before moving to Tokyo, His return brings the past rushing back into focus. Shizuka hasn't aged a day—if anything, she’s become even more stunning. After a warm reunion filled with delicious food and heartfelt inquiries about his life, fate intervenes that evening during a trip for drinks. Yuki witnesses his sister-in-law passionately pleasuring himself while his brother reluctantly resists joining in, giving Yuki a front-row seat to her solo ecstasy. Seeing her unsatisfied desire ignite a powerful surge of lust within him. The next morning, capitalizing on his brother’s absence at work, Yuki finally claims Shizuka! Although she is fully aware of the intense feelings he harbors for her, it’s too late; she belongs to her husband, who reciprocates the love. Yet, how could she refuse? Throughout his stay, the two engage in clandestine encounters that leave little doubt about their burgeoning affair. As he prepares to leave, Shizuka begs him to promise a return date, but Yuki knows he must maintain distance if he ever hopes to truly forget her—a memory that demands an impossible homecoming.
