What is the name of the heroine Gong's TV play?

Gong () was originally just an ordinary junior high school graduate, but he gave up college because of his childhood partner's request (played by Lee Dong Hae) and followed him to the city for development. Bubu worked hard for the singer's dream. In order to take care of him, Gong frantically works three jobs every day to make money, with no regrets. After successfully debuting and quickly becoming popular, Step by Step began to alienate the palace. Finally, I found out by chance that Bubushang was just using her and treating her as a maid. Gong, who was left behind, released the devil in his heart after being hurt by unbearable words. With great resentment, he decided to become a super artist stronger than Bubu Shang (Lee Dong Hae) and knocked him down in Bubu's remaining entertainment circle! Gong chose a brokerage company with equal strength as a springboard for her to become an artist. However, the president thinks that she is losing her lover at the moment, and she has a heart that looks forward to being loved. However, the president didn't want to give up her talent and put her in the newly established department to love me. During this period, I met my first friend Qin, and more importantly, I met a person who had a great influence on my life-Corn Dun.
