Cupid has decided to bring a little Valentine's love to the monsters of midgard… but that didn't go well. Let's just say if you see a couple of passed out monsters around the world, they probably were eating a flower that Cupid gave them… apparently they are kinda like catnip for monsters. But if you are lucky, when you're killing monsters you'll find one that's resisted eating their Valentine's Rose, and Cupid is offering to take them in groups of 12 and allowing you to send them to a special someone. When you send them, he'll turn them in a special hat provided by Gaypuff (a local player). Cupid has a bit of a problem too, all his Heartrings escaped. If you are lucky enough to find one of them, a special prize awaits.
This event ran from February 12th, 2011 until March 17th

Answer: Kill any monster in the game. This means ALL monsters drop the rose at a low chance
Answer: They spawn every once in a while on random Fields & Dungeons. Wait for the announcement, then hunt them down.
