Summary
Rendered in Felix’s artstyle is a man with slightly curly, strawberry blonde hair, long enough to form into a short mullet behind his head. His muscular frame is posed casually, freckles dotting a lightly tanned face and parts of the character’s arms and chest exposed by his loose, ruffled shirt. Round amber eyes stare back through Sylvain’s screen, cocky and challenging and warm all at once.
"Huh," Sylvain thinks. "He looks like me."

Summary
Even after the war's end, skirmishes continued to break out across Fódlan. Learning that there were still places where he could fight, Felix abandoned his noble title and chose to make a living with his sword. Decades later, he reunited briefly with Sylvain, who had need of his services as Margrave Gautier. Felix departed as soon as the job was finished, however, and the two never met again. Years later, a sword that was thought to have belonged to Felix arrived on Sylvain's doorstep.
Along with a letter.

Summary
Goddess—Felix hates Dimitri sometimes. He's stupidly oblivious. Felix wants to shake him until he understands, but he's so focused on his own trauma that it blinds him to everyone else's pain. Felix could just tell him, he would not be able to rationalize keeping Miklan around then, but it is Sylvain's secret, not his, and he can't betray his trust.
Miklan may have everyone else fooled, but Felix can’t stay silent.

Summary
Sylvain sits back in his seat and Felix realizes he’s recoiled against his door as if he was fucking scared, which is the most absurd thing ever. First, Felix is trained in three different martial arts, he’s the best shot in the team, and knows his way around a blade. He’s not scared of anyone. Second, why would he be scared of Sylvain touching him? It doesn’t affect him at all. He can touch Sylvain whenever he wants.
They kissed. So what? It was only for show. Felix is not thinking about it.

“Ooooh!” Sylvain sings, genuinely interested. “LoneWolfBlade has a crush. I’m so proud. Everyone in chat say ooooooooooh~!” He draws out the exclamation so that is has six distinct syllables.

Summary
Here’s the thing: Felix knows he’s not Sylvain’s type. He has no doubts that Sylvain is, at least somewhat, physically attracted to him, something Sylvain has made abundantly clear. However, Felix has no illusions that he is an outlier among the people his boyfriend has been interested in.
Which is why, when the approaching coworker has gently cascading lilac hair, pristine eyeliner and eyeshadow, and clothes that cling tightly to his wiry body, Felix immediately decides that he hates him on principle.

Ashe supposes Felix and Sylvain do work together, if in an oddly dysfunctional way.

Well, Felix's hands are bare.

Summary
Touching Felix felt so good, like slipping between clean sheets after a hot bath. It was weird. Touching his lovers didn’t feel this way. Sylvain’d never enjoyed it anymore than he enjoyed skinning the animals he hunted.
He should question this, a part of his brain tried to tell him.
Sylvain offers to massage an exhausted Felix’s sore arms and hands. As it turns out, Felix might not be the one who needs it most.
