<P> Tawni is probably the only person who initially knew about Sonny and Chad's mutual feelings for each other, but never mentioned it to anybody . Tawni has a secret - she likes Sonny . She is jealous of Sonny's fans . Despite their rocky beginnings, she has since begun to care about Sonny as a friend and eventually as a best friend . </P> <P> She is often seen giving her advice and is shown to be nicer than before, such as the instance of driving Sonny all the way back to Wisconsin in "Sonny with a Secret", but she tells Sonny to do projects for her, shown in "Falling for the Falls (Part 1)". Also, she still doesn't like it that Sonny's boyfriend is Chad, as do all of the So Random! cast . She has been on So Random! for five years . She says that she was homeschooled, and that her mother Tammy (also her manager) was very strict . </P> <P> Chad Dylan Cooper (Sterling Knight). He is the teen heart - throb of Tween Weekly and Mackenzie Falls, and the main antagonist in season one . He is the arch - rival of Sonny and the cast of So Random! early in the series, as well as Sonny's love / hate interest as developed later . He seems to have liked Sonny since the beginning of the show, and in one episode tries to force her to kiss him, before they were dating . </P> <P> He is a spoiled and bratty egomaniac and thinks that he is better than everyone else, and can be seen as effeminate in his obsession with his own appearance . Despite this arrogant, childish behavior, he has moments where he shows he is very kind and deep, especially when he's around Sonny . He became more friendly towards the cast of So Random! because of his feelings towards Sonny, and later, he eventually falls in love with her and starts dating her . However, in "My Two Chads", it is revealed that Chad has a stunt double named Chaz, who he has to go on dates with Sonny that he deems dangerous . When Sonny finds out about this, she dumps him, but they get back together at the end . </P>
