Koisuru Sha Girl

When first year Rikako stumbles upon a senpai in the school's archery range, she finds herself entranced. She decides, on the spot, to join the archery club in order to chase that feeling and meet him again. Except, as it turns out, she's not the only first-year girl with that idea... Can Rikako win him over with her earnestness, or will her ulterior motive be discovered?
