Interesting. This manhwa/manga/webtoon is patterned with the fairytale story, Rumpelstiltskin. Though the only difference is the female lead comes from the real world, and is trying to go back to her own world by following the story as suggested by the mage she met.
Ugh the magician looks boyish and cute. I want to know his backstory. Looking forward to more updates.
