I was pretty sure I've read this before, then I realized that it's the serialized version of it. The pre-serialization art is way better to be honest. Not only that, the ending of the oneshot is sweet with the same dialogue but different setting.
One thing I learned recently is that Jump+ was actually going to serialize this, all the way back in 2022. This was in the files for January serialization batch but set to hidden:
So it was apparently planned enough to get a visual, but ultimately never went through. Then three years later it suddenly got serialized by Akita Shoten with a different artist.
