Hi! There is nothing wrong with your Request Thread in my general opinion, but since I'm frequently viewing Requests Threads myself, I will admit that it's a little bit like being met with a wall of text. A little bit overwhelming. A lot of the things that you say can be simplified, so people who visit your thread see what you're offering and what you seek right away, instead of having to read through two paragraphs. Most people don't bother to read and just click out if it feels like too much.
I would also try to rewrite some of the plots, so it's consistent with MC and YC or characters A and B.
I would also suggest creating a new Request Thread - you can easily just use your text from this one - so it doesn't feel so "old" (I can see it's from 2019). It also doesn't hurt with some visuals (that also makes it more appealing to the eyes and the text doesn't feel as intimidating).
If you'd like, I can put together a Request Thread for you really quick, using the information/text already in your thread? If you're not familiar with coding, you can always reach out to me and I can alter the codes to whatever you like.
I hope this was slightly helpful! Feel free to message me or just comment here if you'd like some help!
EDIT ; there are also not that many people who have the opportunity to reply once a day, so maybe you could also try to lower your requirements to maybe 3-5 times a week? If that's okay with you, of course.
