Alright write/reading fags, here's how it goes down.  This is Pokemon Love Stories: The Bad Endingss.  Based on the Touhou Love Stories variation, it consists of trainers falling in love with other pokemon.  There is no restriction on gender or required genre.  Heck, a relationship can end comically, tragic, or even sarcastically, but the main rule is that the relationship must reach a bad end, no matter the cost.

Here's a crappy example to get an idea of how it works.

You are a male hiker extraordinaire who encounters a female jigglypuff while exploring Mt. Moon.  Surprisingly you two hit it off and became best friends.  When you found a moon stone and evolved her into a Wigglytuff, feelings developed inside of you that you would have never expected to have.  One day, you return to Mt. Moon with her at night and upon reaching the top, you serenade and declare your love for her.  Shocklingly, she returns your surprise affection with a kiss, and later, you two have freaky interspecies sex.  Unfortunately, when she came, she sang at the same time, putting you into a fast but deep sleep, where then you accidentally roll of the mountain, smash your head in, and go into a coma.  On your bed, she cries, apologizing for causing this to happen to you.  Unfortunately once again, she sung out in sorrow, which made your coma turn into death.  For killing a human, she is then arrested and euthanized.  BAD END.

Anyone can contribute to this pastebin, so feel free to post your bad endings to your love life :^).
