The description basically sums it up, this is any writing for NCT ot23 members.
To request just give me a member and what you want it to be about. Feel free to make it as general or specific as you want. Request in the comments or DM me, whichever one you're more comfortable with :)
Here's an example of a request from nozomanai_'s book of NCT Imagines (which I highly recommend you check out if you like these kind of books)
You can also just put like Y/N for who you want the person to be.
That's all I guess, I hope you like the book and feel free to give any feedback :)
