Yamenakute wa Ikenai.

Mayu has recently entered a new chapter of her life by beginning a romantic relationship with a boy she genuinely cares for. For the first time, she has the chance to experience a normal, healthy connection with someone her own age. However, beneath the surface of this budding romance lies a deeply troubling secret that threatens to unravel everything she is trying to build. Long before she ever met her boyfriend, Mayu became entangled in an illicit and addictive sexual relationship with her own father. What began as a hidden transgression has evolved into a compulsive dependency that she finds nearly impossible to break. Despite her sincere desire to move forward and focus on her new partner, the physical and psychological pull of her father remains overwhelming, casting a dark shadow over her daily life. As her feelings for her boyfriend continue to grow, Mayu realizes that maintaining both relationships is unsustainable. Continuing her forbidden encounters will inevitably destroy the trust and future she hopes to share with the boy she loves. Now, she faces an agonizing internal battle: can she find the strength to finally sever her toxic ties with her father, or will her uncontrollable desires consume her chance at true happiness?
