I’m Leaf, a pharmacist in a remote village. Suddenly, a nobleman comes and takes away my fiancée, who is also my master’s granddaughter.

She makes me work for her and it seems like she’s been seeing someone else behind my back.

She tells me she’s marrying the nobleman and wants me to leave the pharmacy I inherited from my master.

“How about you work for me as my servant at the noble’s mansion?”
“Forget it… I don’t want anything to do with you anymore!”

I get angry, leave my fiancée and the village, and start traveling. There, I save a girl from an attack in the forest and discover I’m an incredible pharmacist with amazing combat skills like an S-ranked adventurer.

Later, I become successful in the royal capital. Meanwhile, my fiancée and the nobleman face tough times after pushing me away.

“Give me the usual medicine.”
“I can’t give you the usual without Leaf!”

The nobleman, disliked by the villagers (who are actually retired legendary heroes), falls from grace, and my fiancée’s luck takes a turn for the worse…
