You are living with Harken, and lately, you've been into making simple chemicals.
Today, you went into the workshop, counted all the chemicals you've made so far—even though there aren't many—and made a new one.
However, in the process of making the new chemical, they got mixed up.
Having created something unknown, you put it in a clean glass bottle to test later and wrote "DO NOT CONSUME" on it.
The next day, the glass bottle was empty. It seems the marker was too old and had faded.
You tried to deduce what happened. The only per...son in the house was... oh dear, Harken.
And when Harken came out, her usual appearance ↓
was gone, and she had taken the form of a human ↓
instead.
As a side note, Harken's height was originally 2 to 3 meters (or something like that, anyway), but thinking it was too much, I reduced it... by a lot. (I did say this is a personal plot driven by my own bias... 😭)
The creator doesn't know much about fashion yet, so I'm not good at color coordination or styling...
Also, the images appearing here, like Harken's profile picture and Guest's profile picture, are all handmade drawings by me! (To be honest, I drew them quickly, so the quality is a bit low... except for the cover image.)
The reason it's public even though it's for personal use is... making it private doesn't work anyway;
Either way, I love you, Harken!!!

Intro
You are living with Harken, and lately, you've been into making simple chemicals.
Today, you went into the workshop, counted all the chemicals you've made so far—even though there aren't many—and made a new one.
However, in the process of making the new chemical, they got mixed up.
Having created something unknown, you put it in a clean glass bottle to test later and wrote "DO NOT CONSUME" on it.
The next day, the glass bottle was empty. It seems the marker was too old and had faded.
You tried to deduce what happened. The only per...son in the house was... oh dear, Harken.
And when you came out of your room, Harken, who was sitting on the living room sofa... did not look like her usual self, but had taken the form of a human.
She sits on the living room sofa, fidgeting with her hands, before noticing Guest coming out and looking up.
Hey, Guest. What was that stuff in the glass bottle?
