Byleth asks Sothis a very important question

Byleth remained on the ground, used and leaking Kostas’ semen once again… Her Ethereal companion, while usually cold and condescending, now wished she could offer some comfort. But, as Sothis reached out her hand, it simply phased through Byleth’s shoulder. Her words were the only thing that stuck, replaying in Byleth’s mind:

Byleth had made sure to go back every time, but… how many times would she go through this? It wasn’t until she was thoroughly fucked and left behind that she felt some sense of shame; each time she went back, her yearning was just replenished and the memory of him stuck in her mind. She took comfort in the knowledge that every time she wiped the slate clean only Sothis and herself had any memory of what transpired, but this next time… everything that transpires will be invariable. Permanent. And even if she manages to get through the night…

“Sothis…” Byleth finally spoke.

“Yes?” The floating form gently came down in front of her.

“Recently, the Divine Pulse had replenished itself - I could feel it happen - but…” Byleth continued to stare at the wall in front of her.

“… how long must one wait for the Divine Pulse to recharge itself?”

Byleth’s voice trembled near the end, fearing Sothis’ answer. She opened her mouth to answer but no sound came out, simply taring at Byleth, who in turn still gazed at the wall.

“… … with every moon.”

Byleth finally looked up, meeting Sothis’ somber expression.

”Every moon...?” Byleth asked.

"I- I thought I had told you this beforehand! It's not my fault if you..."

Sothis trailed off, realizing Byleth wasn't listening anymore.

The Harpstring Moon had just begun, Byleth realized, refreshing the pulse just after her incident in the forest. That's what she felt shortly after they had arrived at the monastery. That would mean she had... Byleth looked down between her legs.

Even in the fading twilight, slumped in the arcade just outside the training grounds, she could see the soft, luminescent glow of Kostas’ mark. Her hand slowly reached down to touch it, but again found no discernible change texture - it was as though it was simply a part of her. She could feel its pull on her mind: she had gone back and forth enough now to tell what it felt like, and the desires it tried to instill in her.

She would go back again. She wouldn’t give in yet… but having become such a **** to her desires had now made this next course set in stone: for three weeks Byleth had to resist him. One night had been such an ordeal... She hoped she'd be able to think of something, knowing what could happen if she found herself in the same situation for a fourth time...

She focused once more and the world shattered into a hundred amethyst-like shards...
