As much as I will always love Channy and loved that both Demi and Sterling agree that Channy would eventually end up together and my child-self was crushed when they broke up. Watching them Break-up now that I am older, their break-up made sense and Chad was a narcissist.
P.S. - I have no doubt that Disney was going to give Channy a third chance (no pun intended) or make Chad have a character arc I have my doubts.
Me not really being into the whole enemy to lovers trope but then realizing the biggest ship I liked as a kid was Sonny x Chad from Sonny With A Chance xD
