One day, he scolds a high school girl named Minamisato Karen, which unexpectedly makes her take an interest in him. As Karen gets closer to him, Eiji also starts drawing attention from his lazy middle school sister, his inquisitive childhood friend and ex-girlfriend, and his serious-minded subordinate. As these relationships develop, he must balance them with his job, struggling to maintain the quiet life he once had.
