Sleeping time YCH comic By fairyfud

What does "YCH" stand for in the comic title?

YCH usually stands for “your character here”
artists occasionally sell commissions where they come up with the scenario and do rough sketches first, then people can pay to get their own characters in the places of characters in the sketch as a finished piece. I guess this was that kind of commission

It's absolutely hilarious that her thought process is "Opps forgot the condom now there's a mess." and not "Welp I melted my gf."

Why does this have to be with a bunny & a mouse rather than humans?
