This drama is adapted from the manga of the same name. It tells the story of a young popular actor Shibuya Dahai who has never been in love. He meets a kindergarten teacher Aota Aika while picking up his younger sister who is much older than him. It is a love comedy that breeds love in a clumsy way. Dahai can perfectly control any role and capture the hearts of women in the world with his hearty smile, but he is actually a handsome guy who is a bit innocent. After Aika met Dahai, her daily life with only work and no color began to be greatly shaken. What kind of love story will these two people who are unlikely to be together unfold as "teacher × guardian" and "artist × outsider"...
