Here is what I think. It's either he is jealous of Joon or he is just that type of person that is shitty because he actually likes Joon. Or he .ight be insecure that Joon likes him OR BECAUSE JOON LIKES JONG OH? but I don't think that Jong Oh (blue hair guy) likes Joo-in (greenish brown hair guy) he just said he 'I like you....Joo-in' because he appeared suddenly out of nowhere. But we don't really know that yet. It's either that triangle where one of them likes and they also like them.
I find it funny because this an actual love triangle instead of a love angle where two people fight over one person's feelings. Joon likes Jong Oh, Jong Oh likes Ah In, and Ah In likes Joon probably
