My Sister Disguises Herself as a Man, but I Bind Myself to the Goddess System

Luo Qingxuan, a freshman in the acting department, a straight man with a strong social fear. On the day of registration, a mechanical sound blasted in my mind. "Ding, the goddess system is successfully bound!" "Wait a minute, I kidnapped the wrong person..." "Once the system is bound, it cannot be unbound for life." Because of the system, Luo Qingxuan wore a JK skirt, had waist-length hair, and sang in a girly voice. What's even more outrageous is that his twin sister Luo Qingxue disguised herself as a man to flirt with girls and pushed a bunch of girls' WeChat messages to him. And because of the system, he disguised himself as a woman to participate in the competition, and was regarded as the dream lover of many boys. The system releases the main task: participate in the campus singer competition and win the top three. The punishment for failure is to wear women's clothing for 72 hours and move around in the core area of ​​the campus. He had no choice but to bite the bullet and get on stage. After taking the stage, he saw a purple figure next to his sister who was wearing men's clothing. The purple figure was very clear and clean. Her name is Yuna, a senior in the music department, and she plays the piano very well. She thought he was "Luo Qingxue's younger brother" and came to the music building every day to listen to him practice singing. Until one day, she handed him a piece of piano music with the title "For Luo Qingxuan". Luo Qingxuan was moved. How could he tell her: The "Luo Qingxue" you admire is me standing in front of you?
