She is the only daughter of Minister Bingshan. She is strict with herself, well-behaved, sensible, cheerful and serious. Her name is Tezuka Harumi. He is a famous tennis prince who is determined, confident, mature and lonely. He called Echizen Ryoma. The 20-year age gap made them so close. "Dad, Ryoma-nii is here!" Harumi happily took Ryoma's wrist and shouted loudly as she led him into the living room, "Harumi wants to call you uncle!" Echizen Ryoma corrected helplessly. Harumi's originally happy expression fell silent, she slowly let go of Ryoma's wrist, turned around and looked at Echizen Ryoma seriously and stubbornly and said "YADA" "Harumi is not allowed to be rude to elders!" Tezuka said sternly as he just walked into the living room! "I don't want any elders!" He murmured as if to himself. He raised his head and had tears welling up in his eyes but stubbornly refused to fall. He shouted loudly at Tezuka Kunimitsu, "Sir, you don't understand anything!" He turned around and ran out of the house. "Hey, Harumi!" Echizen Ryoma shouted towards the door, pretending to chase him out! "Echizen!" Tezuka stopped Echizen and said, "This child has been spoiled by me. She will come back when she reflects on herself!" "Bouji, you are too strict! Harumi is just a child!"... She is twelve years old this year and he is thirty-two!
