My Guardian Character Is a Little Strange

*[Abandoned and wrapped up early. Read with caution.]

On the first day that Xuwang Xun, who has lived with the Xuwang family since childhood, transfers to Seiya Academy, two Guardian Eggs appear on her bed, one gray and one gold.

The gray Guardian Egg hatches the same day it appears. The child looks almost exactly like the protagonist of the shoujo manga she likes.

Yujia: Hi, Xun. I'm Yujia. I look forward to getting along with you.

Xuwang Xun: ...

The golden Guardian Egg remains unhatched for a long time. Xuwang Xun thinks it might stay dormant forever, but one day, it finally cracks open.

Nuannuan: Is it the finale already? I can finally come out!

Xuwang Xun: ...

Why does the art style of her Guardian Eggs look so different from everyone else's?

A few tips before reading:

1. The heroine is Suou Tamaki's younger half-sister.

2. Lots of Shugo Chara, a little Ouran High School Host Club. The story starts at episode one of the anime and mainly follows the anime plot.

3. Lots of original settings [Please note], with an old-school Mary Sue flavor.

4. Pairing with Nagihiko, one-on-one, clean romance.

Theme: Everyone will eventually find the Egg of their Heart
