Haha. Yes, this part had me laughing too. ("It's not like there's poison in it, right?") Lol. XD
I know, my prescribed reaction for Green is totally ooc, if not more. But sometimes you just want the guy to loosen up, to show some feelings XD Even though I dislike oocness. So I'm sure the reaction in this comic will be much better. (I already have a feeling... cause I peeked at the coming pages~!)
I don't really know what high-school is, since the school system is totally different here (we just have elementary school, one advanced school (either four, five or six years, depending on how difficult it is) and then another advanced school or university (also depending on if you want to learn a lot or not). The image I have from high school comes from movies and is probably totally flawed. XD (Read: *****y cheerleaders, dumb football players, nerds getting beaten up).
Good luck anyway~!
