Super serious Asahi Suzumura and laidback, easygoing Mitsuki Sayama might seem like an
odd couple, but they made a deal; they'll vacation around the world and when they get
back to Japan, they'll get married.
As they travel from country to country, the different people, cultures and cuisine they
encounter begin to bring them closer together. After all they're not just learning about the
world, but about themselves too.
