Just entered my scenario for Okko's Rental Boyfriend otome writing contest. I went with Kotaro since he's a cutie and I can keep it clean unlike say, writing about Takeomi or Haruka. The hardest part was keeping it under 700 words. Had to change my story around to make it fit. Ended with exactly 700 words. Took me about 1-2 hrs but I was also playing on my tablet a little.
If you still haven't submitted your entry, there's still time. December 6th is the last day.
