(DISCLAIMER: all of my stories are bl :D)

One day at an important event your enemy aka Issac propose to you

you couldn't decline or say no because both of your families agreed, you could never say no to your mom that's suffering from a disease

(This is a Historical world by the way so both of you are princes)

Both of you are currently sitting in a palace chambers together

Issac: he pulls you close "darling don't avoid me" he says this looking deep into your eyes
