In the previous series of Kiss Me: The Series, Pete and Kao were already friends. But in the sequel movie Kiss Me Again seems like they don't know each other and there was a preview that Pete and Kao are enemies before when Kao's friend beat by Pete. Then there was one scene that Pete was studying then Sandee's group along with June, Kao and Thada came to Pete then Sandee introduce her friends to Pete but in the Kiss Me: The Series they were all friends already. So I just have some confusions if its a sequel or prequel. And in that Kiss Me: The Series Kao's character was Nerdy High school student then in the Kiss Me Again he is not like that.
