Did the Pure-Hearted Nonhuman Successfully Turn Evil?

[Mutual tops, nonhumans lean top and humans lean bottom, but the human is the main point-of-view character, so this is tagged as bottom-led. The human is no pushover and is very sharp; she will become a great mage later on.]

Clyso both fears and hates the vine woman who has imprisoned her.

“I used you to escape the witch's control and elope with the woman I loved. I hurt you, and I'm sorry. I'll make it up to you. But please don't hurt her!”

“Let her go. At least don't lock her in the next room. Don't let her hear...”

But the vine woman, Frolavla, won't agree. Clyso owes her blood, and she will make her repay it with tears.

“If you don't want her to hear...then keep your voice down. Cry quietly.”

“Or I can use my vines to gag you, too.”

Clyso escapes again and again, but after learning the truth, she changes her mind. The woman she thought she loved was only a transmigrator who treated her as a target to win rewards. The one who truly loved her all along was her inarticulate vine woman, who had always risked her life to protect her.

So she killed the transmigrator with her own hands and went to ask the vine woman for her reward.

She wrapped herself around her, choosing the red-and-black vines below her waist. “I don't mind being heard anymore... Will you tie me up with this one today?”

Frolavla: ...Damn it, did she just get her off?!

Perletta certainly loves her mermaid girlfriend. After all, she's beautiful and devoted, and she used her enchanting song to help Perletta eliminate political rivals and secure her claim to the throne.

But mermaids don't have legs and can't live on land, which limits their future. For the sake of her own prospects and...her sex life, Perletta decides to dump her and find a new girlfriend.

When she discovers Perletta's scheme, the mermaid, Corolin, turns dark. She pours out the love-forgetting wine Perletta had secretly given her. She drinks a potion, grows wings, and gains the ability to survive outside the sea. As Perletta stares in terror and disbelief, Corolin pins her down with both wings and tail, whispering like a demon.

“Darling, now I can catch you on land, in the sea, or in the sky. Where would you like to start...?”

Some time later, thinking the heartless bad girl must be ready to cry, repent, and beg for mercy, she instead hears her murmur with lingering satisfaction: “Why didn't you tell me you had this side to you sooner? If you had, I wouldn't have broken up with you.”

...Corolin feels like she turned dark for nothing.

Other installments are undecided. There should be an octopus and a unicorn.
