Oguri Shun as Hyuga Toru
The president of Next Innovation. His management skills are neither outstanding nor is his ability to attract large capital or have a long-term view of the future. The website he did as a hobby at home quickly generated cash and he found him a billionaire. Because he dislikes people, he keeps thinking that all those who approach him are after his money. The people around him call him various names, “”billionaire”, “master of mobile games”, “con man”, “eccentric”, “geek”. He takes an interest in Sawaki Chihiro who suddenly appears before him and is completely different from him.
Ishihara Satomi as Sawaki Chihiro/Natsui Makoto
A fourth year Tokyo University science faculty student who is job hunting. She has been a hardworking person since young, studying diligently and living in a down-to-earth way. However, she is tactless as well as shy. This makes it difficult for her to find employment and her job hunt has been a complete failure. One day, she attends a Next Innovation’s company information session, and through a strange turn of events ends up working for Hyuga Toru. His tendency to make remarks that hurt people without giving a second thought aggravates her, but before long, she senses his idealism and loneliness because of that, and starts falling for him.
Aibu Saki as Asahina Yoko
Asahina Kosuke’s younger sister. A restaurant chef. She dropped out of high school and went on to a vocational school for culinary arts. After that she went to California for training and was voted one of 100 promising young chefs. With this recognition of her abilities, she is assigned to be the chef of a newly opened restaurant at the building where Next Innovation is located. She is a rare female in the male-dominated culinary business. She met Hyuga Toru way before her brother and soon falls in love with him.
Arata as Asahina Kosuke
Asahina Yoko’s older brother and the vice-president of Next Innovation. After graduating from Tokyo University, he worked at a major telecommunications company. After that, he met Hyuga Toru who is his complete opposite. Seeing Hyuga’s potential, he proposed that they start a business and Next Innovation was founded. He is mild-mannered, popular and also good at all sports. Because he and Hyuga have different personalities, they do not clash. Instead Asahina is the one who gives concrete form to Hyuga’s ideas. Theirs is a relationship where they complement each other and have formed strong bonds.
Sano Shiro as Yamagami Yoshiyuki
Next Innovation’s accountant. “I’ll give you an interesting job,” that was Asahina Kosuke’s promise to him to get him to join the company. Although he is an analog person, he can change to suit the situation because of his flexible personality. He has faith in Asahina but dislikes Hyuga Toru’s impudence.
