[1] The film is a live action adaptation of the manga series Ouran High School Host Club by Bisco Hatori.

[2] Following the events of the TV series, Haruhi Fujioka, a brilliant student from a middle-class family, continues to attend the prestigious Ouran Academy and to work in its Host Club, a unique club composed of six handsome boys: the princely Tamaki Suoh, cool Kyoya Ootori, playful twins Hikaru and Kaoru Hitachiin, cutesy Mitsukuni "Honey" Haninozuka, and stoic Takashi "Mori" Morinozuka, who entertain their clientele with after-school tea service and flirting.

Having spent a year in the club dressed as a boy and acting as the natural Host, Haruhi is accustomed to its ways but becomes flustered when she learns from a romance magazine given to her by the creepy occultist Umehito Nekozawa that she has supposedly fallen in love with Tamaki.

Realizing that Michelle's problem is loneliness, Haruhi decides to participate in the Host Club's attempt to make her smile again by winning the Festival.

Later, when the Host Club takes a walk by a river, Haruhi unsuccessfully tries to express her feelings but in the process, trips and accidentally kisses Tamaki, much to their embarrassment.
