The don’t think there was a big issue with Chakrit and Kob, more like Chakrit was dissapointed that Kob stop him from his kissing streak. The majority of lakorns he get to kiss his na’ek on the lip, and for him to not get a chance to kiss the number one na’ek of channel 7 is tragic for him, his chance slipped away from his hand.
About Chakrit's co-stars that had gone all out. It's up to them really. I mean if they all striped down for a magazine, I wouldn't want Kob to follow along. There's bound to be a different person in a group. There's always a distintive pea in one pod.
