Tsukamoto Tenma is a second year in high school who fell in love with her classmate Karasuma, but could not confess to him directly and instead uses unorthodox ways to get him to notice her. On the other hand, Harima Kenji, a delinquent, has feelings for Tenma.
Unfortunately, Tenma’s preoccupation with Karasuma ensures that she doesn’t notice Harima’s affection. Both resort to stupid tactics to get the other party to notice him / her that always ends up hilariously and utterly wrong.
