Even when we try not to, we still subconsciously projects our lame feelings through our mediocre fiction so let’s just drop the act right here right now; 

Let me get personal! Like, really personal, let me embarrass myself right in front of you; 

Breaking 4th wall in VNs is so olde - like, everybody’ve already made their own DDLC and everybody knows DDLC didn’t even invent the idea.

Hey, I am somewhat interesting, right? I get self-deprecating, so I’m fun and smart, right? I’m artsy and trendy, right? My drawings are pretty, right? I’m a hidden diamond, right?~

So you’d totally sacrifice me some of your time, right? So you’d lend your hands, right? I mean, you’d write something for me, right? Hey, maybe I can borrow your back for a moment? Hey, how about this, maybe I can have your legs, mine are so tired? 

This whole yandere thing is sooo cringe, I know, but I don’t mean it in a literal way, so it’s fine, right? 

Ugh, really, you can handle listening to someone’s personal baggage for so long just cause they participated in yurijam twice or something? Gross... Guess you don’t have a heart, huh?

Ah, but as I said before — give yourself to me, (I don’t really need you to, of course) and maybe I’d offer you my heart instead? How does this sound? (Hey, lmao, do you enjoy it when people speak to you in questions instead of normal statements?)

Why would I ever do such a thing? But why, of course, because I’m a greedy Archfey; I don’t need my heart anyway, it’s such a pain… 

You know what, I changed my mind, don’t bother. I don’t need your arms and your legs and your head, just give them to my Guardians or Priestesses or whatever they call themselves nowadays. Please them, and then maybe, just maybe, I’d recall my offer next time we meet.

If you really are so heartless you can download this .zip or .rar or app or whatever it was archived as

It’s very straightforward and approximately 5k words short and has slightly different offering outcomes but they all lead to the same one ending; couple of dead-ends are present in case you mess up

And by the way, this whole thing was made by mossinasi who used Ren'Py engine and PeriTune's music
