Kiyoko Naito, a 179cm tall office worker, is an older sister-type girl who is admired by everyone for her crisp personality. When she was a little girl, she used to long to be a princess, but due to her height that increased as she grew up, she is now in the position of a "guard" for the girls around her. One day, one of her juniors at the same company, Takeru Himeno, who had a bad reputation as a "plain and boring type of guy" and was worried about her, told her about a very unusual situation concerning him. She then decides to take a risk for Himeno, who is in fact a very talented man. I'll be your shield, so let's stop forcing ourselves to hide! From the next day on, the two of them are in a true "princess and guard" relationship...? This is a cute and happy love comedy between Princess Himeno-kun, an immensely beautiful boy that everyone looks back on, and his protector, Naito-san!
