That’s his first love… The 9-year-old Young Master, who lives surrounded by his servants, is only interested in his Japanese servant, Tanaka. According to the Young Master, he’s just attached to him since he rarely sees anyone from Japan, the country of Ninja’s. One day, he fell in love with Tanaka at first sight, when he barged into the servant's room and saw Tanaka with unstyled hair. Later, Tanaka became Young Master’s exclusive caretaker after being strongly demanded by Young Master. A cute love romance between a Shota and a natural airhead, now begins!
