Kaito Tanaka, a high schooler whose kindness is both a superpower and a crippling curse, just wanted a peaceful school life. But when his simple acts of decency are wildly misinterpreted by the school's tsundere ice queen, his possessive childhood friend, a shy bookworm, a fiery sports star, and even four of his own teachers, he finds himself at the center of a harem. The catch? They all despise each other, and Kaito's life has become a 24/7 battlefield of jealousy, comedic misunderstandings, and ridiculously ecchi situations.
