Miyabi is fucking awesome when it came to stories like that but that one didn't have suicide tho. They just wanted to get away from everything for awhile.
"Yo Dawg, heard y'all like Deep Shit in your H-story, so artist-san dropped some Deep Shit in this H-story so y'all will react with: 'Whoa, That's Some Deep Shit' at the Deep Shit in this H-story."
Not gonna inquire whether this story is a case of Art Imitating Life, but just maybe instead of driving off a cliff, they should have aimed to kill themselves using "Death By Snoo-Snoo"; when done right, it's Super-Effective.
Alternately, it could be that the Snoo-Snoo was so good that they both decided to stick around this world a little bit longer.
Artist: Yes.
