Tenma Tsukamoto is a student who, like so many others, is madly in love. Her lucky one is Ooji Karasuma, an inexpressive boy indifferent to everything, so she will be forced to fall in love with him by all means. What Tenma ignores is that a whole "King Of The Neighborhood", Kenji Harima, is after her and, despite her strength and courage, is unable to show her feelings.
