Kore wa Uso no Kekkon Dakara

In a society where same-sex marriage is fully legalized, twenty-eight-year-old bachelor Mashiro Kotobuki excels as a premier matchmaker at Mari’s, a prestigious marriage agency. Paradoxically, despite his professional talent for uniting others, Mashiro harbors a complete lack of personal romantic experience. This contradiction constantly draws the scrutiny of the agency’s CEO—who also happens to be his mother—as she relentlessly pressures him to settle down. The situation reaches a turning point when his seemingly ordinary coworker, Kaede Narita, accidentally walks in during one of his mother's nagging sessions. Driven by sudden desperation, Mashiro blurts out a monumental falsehood: that he and Kaede are actually dating. Compounding this impulsive lie, Mashiro is soon presented with a career-defining opportunity to direct a newly established same-sex marriage agency, provided he can prove his capability by tying the knot himself. This unexpected ultimatum plunges the two colleagues into a chaotic pretend marriage. Yet, beneath the surface of their elaborate charade, subtle signs suggest that Kaede is concealing a secret of his own, setting the stage for unforeseen complications in their contractual romance.
