It can be said that it was her way of taking revenge against Xiao Li for disturbing her sweet date with her noodles.
'No! You can't call it revenge, infact she was just helping out Xiao Li. Didn't she want to avoid Shen Yi by joining the play? Now with the lead role in hand, she can easily avoid Shen Yi, right? Hehe- Such a good friend she is! ' Sia thought inwardly.
If Xiao Li had known Sia's inner thoughts, she would have lectured her until Sia became deaf.
In actual fact, Xiao Li just wanted to join the play. unlike Sia, she did not want to play the role of the tree since she knew it was of no use if she wanted to avoid Shen Yi so she only wanted to pick a minor role just so she can escape from the fox's clutch.
Even though they were going to participate in the quiz as a pair, they did not have to study together right? But that cunning fox wouldn't let go of any opportunity to stick to her and tease her. That was why she was eager to avoid the devil's clutch.
