Ganbare Douki-chan: Kakusa Shakai ni Nayamu Kaisha no Douki

Douki-chan's quiet competition for her coworker's attention follows her even into a relaxing getaway. Sharing a bath with her confident junior and glamorous senior only makes her more conscious of the gap she imagines between herself and her two romantic rivals, so retreat seems like the safest option.

Later, the group gathers for dinner with the man all three women are interested in. A seemingly harmless question about swimsuits becomes another round of subtle rivalry, and Douki-chan briefly thinks she may finally have his attention before her junior finds a much bolder way to seize the moment.
