Maid wa Koisuru Hachiya-kun

My name is Hachiya, I'm a normal high schooler. After confessing to my beloved Hanazono-san, I was rejected with the reason, "I already have an engagement arranged by my parents." That person is the wealthy and handsome Ikegai-kun, who also happens to have a good personality. Thinking that I had no chance in a straightforward competition, I, Hachiya, decided to cross-dress as a maid and work at the Ikegai house. My plan is to make Ikegai-kun fall for me and break their engagement.. Thus begins a slightly silly, cross-dressing maid's comedy that leads to a chaotic love triangle (?)
