But in typical OVA fashion, there’s also comedic or fanservice undertones (awkward proximity, accidental touching, embarrassed reactions).

The female cast (the “pretty girls” — likely Yaya, Charlotte, Frey, Irori, possibly Henriette, Komurasaki, etc.) gather together at a pool, beach, or other swim setting.
