Help! I Made Penicillin by Hand, and the Tyrant Thinks It's a Love Spell

[One true pairing + delusional misunderstandings + a sickly, obsessive villain who falls for her on his own + laugh-out-loud survival + medicine and farming]

Wen Suining, a PhD in the sciences, transmigrates into a book and becomes a disposable character forced to test medicine on the sinister hostage Xie Wuwang.

System warning: If you don't save him, you'll die!

To stay alive, she makes penicillin by hand, purifies alcohol, and even performs surgery.

She plans to cure him, take the money, and run. But this unhinged villain and everyone around him keep wildly misreading her, sending the story in a completely different direction!

While she cleans his wound during surgery, his eyes turn red. “Ningning cut open her own heart to save me. She must love me more than anything.”

When she purifies chemicals, the dead soldiers panic. “The princess consort is brewing another peerless corpse poison. How terrifying!”

As she plans her escape route, he strokes her ankle. “Trying to tempt me into catching you? How mischievous.”

Then one day, she has barely climbed over the wall when she's caught and dragged back.

Xie Wuwang pins her in a corner, his eyes burning with obsessive fervor. “You gave me a love curse and made me fall for you. Where do you think you can run for the rest of your life?”

Wen Suining is on the verge of tears. Big brother, it's really just antibiotics!
