The Vongola's Outsider

On the first day, she watched the whole thing as a certain flame-haired boy ripped off his shirt and confessed his love. That night, she met him in a dream, where he became her Guardian Character.

Her first thought was that she absolutely would not transform with him. Who knew if their clothes would burst off when they "Unlock"?

On the third day, during home economics class, some mystery poisonous cake knocked him and the unlucky girl beside him unconscious at the same time, and they were swept into another dream.

This time they ended up at St. Mary's Academy. The good news was that this world had no "X-Eggs" or dangers. The bad news was that she had turned into a three-head-tall pastry fairy.

On the nth day...

Although these increasingly vivid dreams helped her understand her classmate, known as "Tsuna the Good-for-Nothing," better and better, there was one problem!

She discovered that after every dream, he forgot everything they'd experienced together, while she was the only one who remembered. The Tenth Vongola Boss was a total jerk who used her and threw her away! She was never speaking to him again!

There are a few side couples (Takeshi and Kyoko, Hayato and Haru), but they don't take up much space. Skip chapters 35, 39, 59, 67, and the final bonus chapter if you don't like them.

Theme: Understanding each other's feelings is what matters most.
