It's great to see you back at it again, and this one seems like much lighter fair than your last story, too, which should make for a nice change of pace, I would think.

I like how it was hinted at that Lily and Sara were in on the shrinking shenanigans, only to find out that they had no idea. The way Lily asked Mike to do all the drinking for their team made me instantly assume this was a trick to get Mike tiny, but her surprise and Mia's need to explain what's happening make it pretty clear this was just a coincidence.

The same thing is true with Sara warning Evan about laying off the jungle juice. That "Just remember I warned you" sounded like the teasing of someone who knows what's about to happen, but her reaction to Evan's shrinking would imply that this, too was a coincidence.

I think part of the reason I like this is that it sort of led readers to believe that both girls were part of something mischievous (or maybe even sinister), only to reveal that they're just as in the dark as the boys themselves. This probably bodes well for the roommates, and probably means that this story will, at the very least, have some gentle elements to it (I kind of like that the tagging for this is vague; despite this being a popular scenario in this fetish, I really have no idea where you're going to go with this). That's what I'm pulling for, anyway. The relationship between shrinking and sororities is pretty infamous (or incredible, depending on what you're into) within this fetish, so it might be nice to see a different take on this scenario this time (although, if this thing does go this route, I'm probably still going to be pretty into it, honestly).

Of course, Mike is obviously going to have to deal with the payback of constantly ripping on Lily's shortness as he goes down, a classic but always fun trope to play with. Mike himself seems like he might be a good dude, once you get past all of that douchey jock energy. I really think he was trying to help Evan out by dragging him to the party, even if it was a dick move to ditch him.

This experience might be the sort of humbling Mike needs to grow up a bit.

And, of course, this also presents the perfect opportunity for Sara and Evan to bond. From what little we've seen, she does seem to genuinely care about him, as she noticed him enough to realize that Mike ditched him when they first got there. It'll be interesting to see just how into him she really is.

We know even less about Mia and Amy so far, but they seem pretty tight. It sounds like the shrinking serum was added to the jungle juice as part of some sort of trial run for her mom's company, and Mia already being clued in on that means she's probably pretty trusted by her friend.

I also like that these two give off slight "opposites attract" vibes (not necessarily in a romantic sense, but generally). Amy is clearly a little shy until she gets some alcohol in her, and Mia shows a lot more confidence (on a side note, I think you had a little mix up where you called Mia Amy during their introductions to Mike). I'm curious to where, if anywhere, that dynamic goes.

But once again, I'm impressed by your ability to make me care about these characters, despite us not knowing much about them yet. In a pretty short amount of time and without having them really do anything special, they all already feel like unique characters, and I find myself rooting for Mike, Lily, Evan, and Sara, even though I'm not even sure what the best outcome for each of them actually is yet (I mean, I've got some ideas, but I don't actually know enough to know if what seems obvious actually is yet)!

I also find myself wondering how the shrinking serum works. Will the amount of it that's consumed dictate how small someone gets? We know Mike drank a lot of it, but we don't really know how much Evan drank past those first two cups. Or does the serum buck that trend and work a different way entirely? Even if this is a lighter story than Micro Cities, I'm sure you probably have all of those specific details worked out already. It's hard to turn that attention to detail off, after all!

And, obviously, the biggest question that will need answered is whether those shrunk will be able to grow back, but based on the way the story summary was worded, I've got a feeling that this is a temporary situation for the guys.

Finally, I'm curious as to whether Amy, Mia, and whoever else (if anyone) involved in this shrinking have taken any safety precautions for the shrinkees. Surely Mike and Evan weren't the only two people to drink the juice, and having that many people running around (especially at some of the sizes tagged for the story), it's going to be pretty hard to keep track of everybody. Then again, maybe the serum wears off itself and makes tinies more "durable." Or maybe Amy and company don't really care about these people. There's several possibilities here.

Again, it's good to jump into another one of your stories, and this is a great start!
