オレん家のフロ事情

Tatsumi, a responsible high school boy living alone, rescues Wakasa, a handsome merman, from a polluted river and lets him stay in his bathtub. As Wakasa’s quirky aquatic friends—like the shy shark Agari and playful octopus Takasu—visit, Tatsumi’s quiet life turns chaotic. Balancing school, rising utility bills, and Wakasa’s spoiled antics, Tatsumi navigates their odd bond, blending humor, friendship, and a touch of romance in this charming tale of a boy and his unexpected bathtub guest.
