Summary
The scar had grown so deep by then that it had become an open, bleeding wound.
On the ground, a blanket of the brightest flowers covered the garden after consuming the remains of her.
And there stood Death, her expression skeletal and grim.
Yet anyone close enough could see that, unlike her face, a deep, intense, and shadowed battle raged within her tear-filled eyes.
Then she understood why mortals feared her.
She understood why mortals begged.
And she understood that, in that moment, her black heart had stopped beating — and with the weight of loss, she vanished into the shadows, leaving a trail of silence in her wake.Chapters: 1/10

Summary
Rio Vidal thought she was just starting a new job—until she met Agatha Harkness. Brilliant, untouchable, and impossibly alluring, Agatha runs her empire with precision… and a penchant for keeping Rio under her watchful eye.
What starts as mentorship and subtle indulgence slowly becomes something more intimate: surprise gifts, private spa trips, and quiet moments that leave Rio craving more. In Agatha’s world, desire is measured in control—and surrendering to it might be the most dangerous choice Rio has ever made. -

Summary
“My turn.”
Agatha rolled up her sleeve, slower than necessary, and fumbled with the stethoscope like she’d never seen one before. Rio was sweating through her shirt.
“Be quiet.”
“Ninety over one-thirty. A little high,” Agatha said, pushing her glasses up. “You’re flushed. You okay?”
“Too much coffee” Rio blurted. Please, God, let the gay panic stay contained for at least five more minutes.
Or: Rio Vidal is a med student surviving on too little sleep. She’s also hopelessly in love with her very straight best friend, Agatha—brilliant, charming, and completely clueless.

Summary
On Monday, there was a flower on Agatha’s desk.
Agatha stared at it, perplexed and suspicious and annoyed, although the hangover was at least partially responsible for that last one. Still, she was not the sort of professor that encouraged gifts from her students. It made them think that she might like them and she couldn’t have that. Then they might try to talk to her outside of class hours or think she might be their mentor or something horrid like that.
The innocuous pink and green flower was a bad omen. It had to go.
Someone keeps leaving stuff on Agatha's desk and Agatha is confused, suspicious, and a little flattered.

Summary
The witch woke up and immediately couldn’t see. That wasn’t the best way to be woken up. A rather concerning way if it weren’t for the scent of evergreen near by and the tingle in the air that alerted her of her former companion’s presence.
Her hands were bound by what appeared to be silk and she was in sheets that didn’t feel like her own. Meaning she was taken by her old lover as well as deprived of her sense of sight.
“Was this really necessary?” Agatha asked with a sigh, listening as a slight rustle of a cloak or a skirt gave away her location. She was close to the bed if her hearing could be trusted. “You could’ve asked for me to see you.”
“Would you have come?” Rio asked.
The answer was no Agatha probably wouldn’t have come. Not unless she was severely desperate to be laid and she had gotten pussy not even two nights prior so she wasn’t exactly starving for it.

Agatha wakes up without her eyesight and restrained in her ex wive’s bed. Rio wants to see her and Agatha just wants to cum and leave.Title based on Chappell roan’s my kink is karma
