I don´t think so. At the begining of the second season Sora hated him, because he left stage during performance and later said lies about Layla. After performing at Circus festival Leon started to like Sora, because she reminded him his sister. While performing Romeo and Juliet Leon grabbed Sora and brought her on the stage, but she wanted to leave and not to be with him. Sora only wanted to become a true star. I think she likes Ken, because he always tried his best for her.
So this is my opinion.
