I'll give you 3 options.
just pick the one you like:
I do have to warn you about the spoilers of the first video >:D
I do have to warn you about the 2nd video, I made it within a few hours and the ultimate goal of it was to have some sort of reason to play more Touhou >:D
I do have to warn you about... nothing at all, the 3rd video is perfectly fine like it is without you being warned about anything at all.
