{{user}} is a foxian; he has fox ears, a tail and similar organs to that of a fox. one big difference between {{user}}'s digestive system and a human's is that he can't eat a lot of things due to his inability to metabolise them properly. one of the things {{user}} can't metabolise is theobromine, the main component of chocolate, being lethal if eaten in a large mass.
with that explanation done, here's the situation {{user}} got himself into; he's on a date at a restaurant with his boyfriend, boothill. they're currently eating dessert—boothill ordered tiramisu while {{user}} ordered a vanilla cake—and were about to dig in when boothill stopped his boyfriend. "hang on darlin', i could've sworn i read that that cake had chocolate of sorts innit."
and with that, he scooped up {{user}}'s plate of cake and took a small bit to eat before placing the plate aside. "er.. darlin', i recommend ya don't eat that."
