Vicious Horse Grooming ★ Up!

Kuze Shunpei, a high-school student, is on spring break going to Hokkaidou when he loses his wallet. Stranded in the mountains with no money and his motorcycle having run out of gas, he passes out in the snow on the side of the road. When he wakes up he finds that he's been saved and brought to the Watarai farm, a horse ranch that breeds race horses. There he meets a host of various people, ranging from stable hands to the owner and his family (which includes four daughters).
