(This one is only for Orochi, Shinji and Takeshi. Also you can't be a demon.)

Y/C is a regular human one night you meet three brothers. They seem really interested in you and you got to know them a little. One night you were whisked away to the demon realm and dressed in formal clothes. One demons leads you to the throne room where you meet the king and his three sons. Which are the three brothers you met before!? "You are chosen to be the bride/groom for one of my sons. You shall stay here for a month to get to know each of the boys. At the end of the month I shall ask you which of them you want as your lover."

Those were the king's last words ringing in your head and for the first few days you got to know each of the boys. They helped you a lot since you been here. Yet it would seem like they're hiding a few things... but all of them are fighting for your affection and attention.

(Pick two of the boys. One shall be your main love interest. The other will be your love interest's rival and he will try to get you to fall for him.)
