Summary
“Moondae, please survive!”
"Don’t do this, Moondae!”
“Moondae, I love you—please!”My lungs felt like they were collapsing as I ran and ran.
Please don’t hurt them. Not my kids.
Not my Testar.
I heard their screams behind me, their voices breaking as they shouted my name when I fell.
Please… just run. Escape. Don’t come back for me.The air around me was freezing, but my body burned...
from being chased,
from being exhausted,
from being terrified.I hated this.
I hated this so, so much.
Please… let this end.God, if you have to take someone, if you demand a sacrifice
Take me.
Just not them.
And then…
the world faded.Or a sudden zombie apocalypse breaks out while Testar is on a break and they do what they do best, try to solve eachother's problems together.

Summary
“ We should date “
“—Hukk!!” I nearly spat out the hot tea the moment I heard that proclamation, my teeth accidentally hitting the edge of the teacup I was holding, causing nearly half its contents to spill all over the table.
I lifted my head and stared at him. Honestly, I didn’t know what I was expecting, but… there he was calm and composed, his expression unreadable, sharp eyes piercing straight into my soul. I tried to return his composed gaze, but failed miserably.
“… w-what ? W- What d- did you just say ? “ damn I stuttered
“ We should date “ Cheongryeo repeated flatly, with no hint of mischief or nonsense in his voice… and those eyes…
“…..” what ? What is this madman spouting about now ? Is this real ?
This is the most bizarre and disturbing thing I’ve ever heard come out of this guy’s mouth and that says a lot. For the first time ever, my brain completely stopped working.

Summary
Myosotis (/ˌmaɪəˈsoʊtɪs/ MY-ə-SOH-tiss) is a genus of flowering plants in the family Boraginaceae. In the Northern Hemisphere, they are colloquially known as forget-me-nots. Forget-me-nots symbolize true love and respect. When you give someone these tiny blooms, it represents a promise that you will always remember them and will keep them in your thoughts. They are also considered a symbol of fidelity and faithfulness.
Ryu Gunwoo is a beta who has just failed the civil servant exam yet again. He managed to drink himself to sleep, only to be met with an unfamiliar apartment filled with toys and kid’s art supplies. When he gets up and tries to assess his situation, a chill goes up his spine. There are photocards of VTIC’s Cheongryeo (why does he have a stage name now?) pinned up, VTIC merch, signed copies of albums… There were a lot of pictures as well, with a girl around seven years old with black hair up to her shoulders. There were a few with a man with dark hair and amber eyes, presumably her mother.
Wait.
…Why was that mother’s face staring back at him in the mirror?
