Pete and Ae couple were pretty boring to be honest. They were both good guys and stuff but I can say that the author didn't give much depthness to them. Pete's character was an unreasonablely shy guy and Ae was a stereotypical hero. I liked the Ae character because the actor playing him did a great job but I can't say that about Pete. Sorry but his smile is like when I'm forced to smile at a school photo. I didn't watch other series of him but he annoyed me here.

I watched the series because of Tin and Can however something annoyed me at the final episode. Can kisses with Tin but he still can't date him? Like how immature you can be? I think he is so cute but his actions and age don't really match. I think both of their characters were unrealistic and cliche as well. However we get to learn more about them compared to Pete and Ae. Well I might be wrong because I skipped Pete's scenes lol. It was fun to watch TinCan.

Kengkla and Techno... I like Techno and it really made me angry how his brother literally let Kengkla rape him. I hope in the 2nd season Techno will beat their ass.

Pond, Good and ChaAim are my favourite characters lol. We can say that Pond is kinda sexist however he is a nice guy actually. I think that's what makes him realistic. He is flawed but still better than that Kengkla guy. I enjoyed and laughed during his scenes a lot. ChaAim is a really cool girl and they are the couple with most chemistry in this series.
Good may seem like a charicaturised character however he reminds me of a classmate of mine. They are both very blunt and slow. I would like a main character like him in a series because he is ICONIC.
