34-year-old Samejima Reiji is the successor of a traditional Japanese inn and a company president who has expanded the business into the hotel industry. Although he is wealthy and able to make guests satisfied, females who get close to him quickly leave once they know about his arrogant and childish character. Then one day, his first love Shibayama Misaki arrives. She is a mysterious female who cannot read situations and he does not know what she is thinking. Even so, he wants to be loved by the person he likes and pursues her with romantic tactics which are too lowly. He used to think that he is always right.
