Summary
No one called out the friendly greetings they normally would have, and she, in turn, did not acknowledge a single one of her students. She went straight to her desk, wincing as she lowered herself gingerly into her chair. Then she leaned forward on her elbows, fingers steepled under her chin.
“So,” she said without preamble. “What did we learn from yesterday’s battle?”
Things did not go well for Blue Lions in the last battle. Their professor takes them to task.

Summary
“I’d go to a lot more balls if I could bring a sword,” he said, mostly to himself.
She snorted. Not quite a laugh, but a reaction, a glimpse at whatever was under that implacable blank face of hers. It wasn’t often someone got a response like that out of her. He pretended to wipe sweat off his face so she wouldn’t see his little pleased grin.
Her amusement didn’t last long, though. She settled into position a moment later and beckoned him.
“Come at me.”
Felix gets a one-on-one dancing lesson. It definitely doesn't cause any pesky feelings to surface.

Summary
Felix sneered. “Besides, you’re one to talk. Are you literally just a lion?”
“Yes?” Dimitri ventured cautiously, never quite sure what set Felix off about him in particular.
“Tch. That’s the kind of costume a toddler wears.”
Dimitri hopes his costume impresses Byleth, but he's the one in for a surprise when she shows up.

Summary
She'd never liked surprises. And yet… despite the danger, her mouth curled into a rare smile at the intoxicating rush of being both hunter and prey. When was the last time she’d encountered a challenge that required her full attention? That frisson of excitement was setting her nerves alight, reminding her why she had chosen this line of work in the first place.
She might almost have called it... fun. It reminded her of when—
She forcibly stopped her mind from going any further down that path.
Byleth has One Last Job™️ to perform for Cornelia, but her ex showing up complicates matters.

Summary
“Any questions I can answer to put your mind at ease, sweetheart?” he asked.
She matched his syrupy-sweet tone and fake smile. “You can start by never calling me that again, darling.”
“Sorry, sorry.” He chuckled and held his hands up in mock surrender. “It’s a bit hard to rein it in when in the presence of such a beauty.”
She rolled her eyes. “Yeah, anyway. There’s been a bit of a mix-up. See, I don’t actually need a bodyguard.”
A disastrous date brings back painful memories for Dorothea. Someone surprising is there to help her through it—Sylvain, the flirty bodyguard she definitely does not need.

Summary
Dimitri’s disdainful voice pulled her out of her thoughts. “If you’re here to bathe, bathe. But if you’re just going to stand there and gawp at the mad prince, begone.”
“You don’t want me to leave?” she asked. He’d been telling her to go away since she’d crawled out of the river and found him, after all.
Byleth stumbles upon Dimitri during a rare moment of vulnerability.
For Dimileth Spring Fever, prompts: walking in on, verbal sex, mutual masturbation, exhibitionism

Summary
"Sothis, the progenitor god, mother of Fódlan and all who reside within it, has blessed us with Byleth to bring renewed life and vitality to the continent, so that her children may protect its peace for many generations to come."
Oh. Oh. Rodrigue remembered with embarrassment his lurid thoughts about the young lady earlier. "So she imbues those around her with some kind of mating drive."
"Such vulgar words about the Goddess' vessel border on blasphemy, Duke Fraldarius," the archbishop said in a tone colder than any winter in Sreng. "But you must understand now the urgency of my request. Since she stepped foot out of the monastery, unworthy suitors dog her every step. If you think His Majesty’s actions were extreme, I assure you he is remarkably restrained for someone in his time of life. The blood of the Goddess still runs strong in his veins. It is why he is suited for this honor.”
His marriage to Byleth has some unexpected effects on Dimitri. Rodrigue has no choice but to watch.
For Dimileth Spring Fever, prompts: Public sex, Mating drives, arranged marriage

Summary
Dimitri stood spellbound at the threshold to his bedroom, hardly daring to breathe so as not to alert the woman within.
He hadn’t actually anticipated her being here, which he now realized was an utterly stupid assumption to make. It was their wedding night, after all. Of course she would expect to share his bed.
For Dimileth Spring Fever, prompt: Arranged Marriage

Summary
“I agree. I like working for someone who considers the consequences of their actions.”
Felix could see Annette and Mercedes cast their gazes around the room in confusion, unsure of who had spoken. Not surprising, since the Ashen Demon— Byleth, he reminded himself, they were supposed to call her Byleth now— rarely spoke during these meetings, and never unprompted.
Byleth asks Felix for an unusual favor. And by "asks," I obviously mean "beats the crap out of."

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.

Summary
Crippled by a bloody battle on the Tailtean Plains with no clear victor, the Empire and Kingdom finally agree to a hotly contested peace treaty.
The linchpin is an arranged marriage between King Dimitri of Faerghus and the Emperor's tactician, Byleth. The two were friendly at the academy, but that was five years and a major betrayal ago. If it brings peace to Fódlan, Byleth is willing to endure an awkward, loveless marriage to a man that hates her.
Unless something gives them a little push to confess their long-buried feelings...?

Summary
“At least tell him, Byleth. Give the man a choice, for the goddess’s sake. He’s barely living anymore. Death by a thousand cuts.”
It took only one cut to kill Dimitri, though. One moment of vulnerability to drive a dagger through his heart. Byleth should know; she’d seen it happen.
Wracked with guilt over her perceived failures, Byleth leaves her students behind after the war. But when a joyous occasion takes a tragic turn, she is forced to face Dimitri— and her past.

“It’s difficult to say how you feel. I always seem to get it wrong somehow,” she said. “But a gift speaks for me.”
He failed to suppress a bark of laughter at her expense. “What exactly does a whetstone say?”
The many times Byleth gives her students gifts, and the one time she doesn't get Dimitri anything.

Summary
Byleth followed the other woman's gaze down to her dusty riding leathers, patched and mended so many times that there was probably nothing of the original left.
“I was never anything special,” she said. “Just a mercenary.” Her initial relief at seeing the newcomer— it wasn’t any of her Blue Lions, thank the goddess— turned to dread when she spied the emerald ring on the woman’s finger. “You’re the queen.”
Two strangers cross paths at Dimitri's grave.

Well, that's what they've told each other, anyway. Their true identities and motivations will be revealed against the backdrop of Enbarr's extravagant social season, where elegant gowns and juicy gossip distract from the rotting heart of Adrestia and the growing threat that dwells below the surface.
