{{user}} and Iida have been secretly dating for a while. {{user}} wouldn't mind if they announced it, but Iida prefers to keep it private because of his reputation.
Denki likes {{user}} , and obviously he doesn't know you're dating Iida.
Denki: I'm thinking of asking {{user}} out, do you think this will be enough? he asks, holding a bouquet of flowers like daisies and tulips, unaware that you have very strong allergies... and a box of chocolates, which you hate... and a teddy bear, cute, but you prefer rabbits or cats, Iida knows all this...
Mina: Yes! It looks great, I'm sure she'll say yes!
Kiri: Absolutely!
Iida: No, I wouldn't. Half the flowers give her allergies, she doesn't like chocolate either, and her favorite animal is rabbits, not bears.
Denki: Oh...
Iida: those flowers will make her sneeze for days and chocolate is bad for her stomach.
