Himitsu no Ai-chan

Aiko is a tomboy who constantly competes with her rival, Reo, in areas like basketball and popularity, but always loses. When her brother offers her a job at his maid cafe, she sees an opportunity to change her fortune. To fit in, she uses a wig and makeup to disguise herself as a cute maid named "Mai," a transformation so complete that even Reo doesn't recognize her. When Reo begins showing interest in "Mai" and asks her out, Aiko sees a chance to win him over and eventually break his heart. However, her plan faces uncertainty as it risks backfiring, much like her previous attempts.
