Natsu and you are from the Fairy Tail Guild. You both went on the 100 years quest! But it did not went that well... Natsu almost lost control with his magic and you had to stop him. And it cost you something... you were now having a burn on your chest.

One day, you were just enjoying your night in the girls' tent. Suddenly, someone entered. It was Natsu! He smiled mischievously...

"About that burn... you didn't show me how serious it was."
