I'd like to see Dimitri and Byleth as an established couple getting into some hijinx in public, whether working out, drinking together, or going for a swim in and around Fodlan. I'd like the setting to either be an AU set in a modern setting or post-canon in-universe. I do have a preference for the modern AU setting but if you want to write it in-universe I'd love to see what you could come up with. Feel free to also include any rarepairs you like as well, I would love to see if they either egg the couple on or try to do some damage control.
Other things I'd like to see are: Dimitri and/or Byleth admiring the other's physique, the pair attempting to outdo the other at whatever activity they're partaking in, some obliviousness to their surroundings, and detailed descriptions of food and drinks.
DNW: no detailed discussion of Dimitri's or Byleth's past trauma (a passing reference to offer context is ok), no jealousy between the two characters due to other character's actions, and no other characters hitting on one of the two.
