Yubin shares the difference between group and solo promotions in 'Cosmopolitan'

Yubin opened up about going solo. 

For the January issue of 'Cosmopolitan,' the former Wonder Girls member, who recently made a solo comeback with "Thank U Sooo Much," perfected the girl-crush look with stylish blue hair. 

In the interview, Yubin shared the difference between group and solo promotions. She said, "I feel more responsibility since I have to fill the stage by myself. I have started working out to boost my strength, and continuously took vocal lessons. Also, during the days with others, I was used to yielding but now during solo promotions, I try to clearly state what I wanted to do. I'm going to get greedy. I think I'm getting used to working alone now."
