Red

You have received white roses painted red from a messenger from the Queen of Hearts' castle/the flowers were sent to you by Red who thinks he is winning you over with his details, but since you don't know this you think it's a threat from them. Who would send something like that, painted roses? You are confused and worried, you know you have to do something.
(Ideas you can go to the castle of hearts to find out what happens or you can respond to the flowers with a letter or something)
