Posted! And I have no idea how laughing gas feels like, but I'm assuming this is as close as I'll get!
And hm...Seven Deadly Sins, you say? Alright, when the occasion arises, I'll make it evident...ahaha.
Anywho, the post might be edited when I'm in a more productive state of mind, since it's written at a time like this ahhhh. This is the basic skeleton, and may or may not be fleshed out. But I felt I absolutely [i]had[/i] to post, y'know? My inner writer would not let me not. 
I hope I can flesh it out and make little details within later edits, if there are any!
Thank you, and good night! <3
