Kang Ha-gyeong, a river dolphin beastman who has lived his entire life in the countryside, becomes stranded in Seoul after being scammed by an old friend with a fake job offer.
And just then, a large man approaches him.
“You’re hired. Start working here.”
Unexpectedly landing a job in the most unforeseen place, Ha-gyeong finds himself enjoying his new life in Seoul more than he ever imagined, completely losing track of time.
But then, a major trial strikes Ha-gyeong.
He ends up falling head over heels for his boss — a man who seems to have a rather dangerous job, is a slick city guy, and not to mention, a fellow sea beastman.
Can Ha-gyeong overcome this trial in the form of a man and find his happy ending?
A tender love story of a brave river dolphin.
