Love Debugging

Forced by his sister's threats, Cherry sets off on a trip to Paris through a travel app—only to run into his all-too-familiar rival, Lemon, in a completely unfamiliar place. Determined to ignore the infuriating Lemon, Cherry unexpectedly meets his assigned partner, Peach, who happens to match his ideal type perfectly. But just as Cherry begins to fall for Peach, an error in the travel app throws everything into chaos—and suddenly, Cherry, Lemon, and Peach are all registered as each other's partners at the same time!
