Fics like The 100 Umamusume Who Really, Really, Really, Really, Really Love You

Aijou Rentarou did the impossible. After finally reaching one hundred soulmates and proving that his love, devotion, and sheer compassion could defy cosmic probability, the God of Love appears once more—not to punish him, but to offer him a new purpose. With a single choice and a flash of light, Rentarou finds himself far from his familiar world and standing in the office of Tracen Academy. No longer tasked with loving one hundred girlfriends, Rentarou is given a new, equally absurd mission: achieve the “Good Ending” for one hundred trainees. Thrust into the world of Umamusume—where burdens are carried and smiles often hide unspoken struggles—Rentarou must navigate tracks, training, and the hearts of those who run upon them. As fate tugs at his heart when he locks eyes with a certain green-clad secretary, one thing becomes clear: whether as a boyfriend or a trainer, Aijou Rentarou will not rest until every last one of them is happy. Or... Rentarou is willingly sent to the world of Umamusume, his new goal being to get the Good Ending for one hundred trainees. He'll cure trauma, expectations, etc. Maybe there'll be a bit of dating on the side... ... Natsume Kafka strikes again!
