The Sister of an E-Sports Genius Is a Star?

I am a boy with a soft personality and cute appearance. I am only about 163cm tall. My academic performance is not too bad. People around me like me very much. But what they don't know is... I am currently the number one player on the Perfect Ladder rankings. I am not an only child. I have an older sister at home. I look very similar to her, and I am often mistaken for a girl. But she and I are like people from two different worlds. We are ten years apart. When she was sixteen, she persuaded her parents to go to South Korea to become a trainee. Two years later, she made her official debut in Korean entertainment and was called a "monster newcomer." After another year, she returned to China to develop, and she appeared on the most popular variety show in the country, and she became very popular. It was then that the conditions at home began to improve, and I also got my first computer... I started playing various games such as CF, Overwatch, PUBG, etc., But gradually I started to only play one of my favorite games... And the game I am best at: counter-strike.
