Tanaka to Mizuno wa Wakariaenai

Hirona Mizuno, the top runner in high school track and field, has a secret—she's in love with her junior, Tanaka. However, there’s a major problem: Tanaka is completely obsessed with track and field. His dedication to the sport is so extreme that he remains utterly oblivious to Hirona's feelings. No matter how hard she tries to get closer to him, their hearts never quite align.
