Late, but I wrote some smutty semi-public omegaverse for JustWantSauce for the #DimilethExchange! Dimileth make terrible decisions at an opera. archiveofourown.org/works/79400041

Watchfulness dpsisquared Summary: Jeralt sometimes joked that her eyes had grown so large because she was always looking, watching, absorbing the details of the world around her like a sponge. Words could be twisted, honeyed, and misleading, but bodies and actions couldn’t lie. Byleth got all the information she needed about someone from observing them, so, efficient as she was, she simply skipped the talking part. Byleth's eyes have always been drawn to Dimitri. At Gronder Field, she can't believe what she sees.

Also squeezed in a treat for a friend right before reveals! Golden Deer Student!Byleth reunites with her old flame in dramatic fashion at Gronder Field. #dimilethexchange

He calls upon the Ashen Demon for their services (and discretion) to assassinate him. However, they have a specific condition that must be fulfilled to carry out Dimitri's request: the payment must be made in small amounts, spread over time and presented as a gift in front of Dimitri's confidantes and retainers.

Mother, Mother, Have I Boiled the Frog Enough? Rating: E When Lambert announces his sudden engagement to the elusive Byleth Eisner, Dimitri swallows her discomfort and resolves to be a good daughter, even if it means welcoming a stranger to the family. To her surprise, Byleth is pleasant, and Dimitri starts to see her as the mother she never had. The idea of Byleth being family soon becomes appealing. Until it all goes awry when Dimitri’s affections twist into something perverse.

A Meeting, A Rediscovery EtherealWill Summary: In 1170, Jeralt meets an old friend, Lambert, while Byleth plays with Dee. In 1180, they meet again at Garreg Mach and learn something about each other.

Two panel comic. In the first, a young Dimitri and (female) Byleth are play swordfighting while Lambert and Jeralt look on; they are approximately 8-10 years old. In the second panel, Dimitri and Byleth are now around 18-20 years old and at Garreg Mach in their student uniforms. Dimitri is now taller than Byleth. Dimitri looks surprised and Byleth looks pleased. They are both blushing faintly.
