Shinyuu to H Shite Mimashita

After finally gathering the courage to confess his feelings, Takahiro successfully enters a relationship with his close friend Kei. However, their romance carries an unusual dynamic, as Kei’s affection remains somewhat one-sided despite them officially going out. More importantly, the couple faces a strict boundary regarding physical intimacy. Their first attempt at being intimate together ended poorly, leaving Kei in significant pain and prompting him to establish a firm rule that they must never try again. For Takahiro, this restriction becomes a source of deep frustration and longing. Unwilling to accept that their physical connection must remain permanently off-limits, he grows increasingly determined to change Kei’s mind. His desire to share that closeness with the person he loves drives him to extraordinary lengths. Takahiro resolves to do absolutely anything necessary to prove his devotion and gently persuade Kei to give them another chance, even if it means pushing himself through grueling challenges like winning a marathon to demonstrate just how far his dedication truly goes.
