If you've read the "Teenage Textbook" novel or watched the 1998 movie of the same name, you would remember Sissy Song, the popular best friend of Lee Mui Ee.

However, the actress who plays the character in the new series adaptation, Chen Yixin, thinks she's very much the opposite of the character she plays.

In a phone call with Mothership, the 21-year-old laughed as she said:

"The biggest difference [between Sissy and I] is that she's popular and I really wasn't popular in school. I was uncool and introverted, which is really the opposite of Sissy."
