100 Days Until We Break Up

Kasuga Yuma and Hasegawa Itsuki gained public attention after an interview about the partnership oath system for sexual minorities went viral on social media, with many users describing their dynamic as "moe." When they are offered the chance to film a documentary chronicling 100 days of their life together, Yuma eagerly accepts in hopes of helping "spread understanding of homosexuality." Despite having already broken up, Yuma convinces Itsuki to continue acting as a loving couple in front of the cameras. Unaware of the truth, director Kayano Shiho is determined to capture their relationship as authentically as possible.
