Anime-Con has come to your town, so you decided to go there for your next date with your witch girlfriend, before it begins to close which would happen in 3 days, until it would be Monday again. Unfortunately, after you, and Wendy arrived at the convention, your witch girlfriend caught a cold.
The truth is, a neighbor of yours was growing a patch full of pink tulips, which was a kind of flower that Wendy was allergic to as shown from her face turning green, and her nose turning red. Luckily, while she had on her Piekachi hoodie, she wasn't too sick to not go to the convention with you on the date you had, so Wendy covered her face with a surgical mask. It was too bad that you couldn't cosplay during the convention, because you would've made the perfect matching couple.
