Why were they calling each other so affectionately? To answer that, we need to rewind a few months.

After their first meeting in Sky City, Muse and Hefei had become pen pals.
The two little dragon girls communicated regularly via dragon messengers.

At first, they kept it a secret from their parents. That is, until one day, Konstantin noticed his daughter stashing an assortment of fancy envelopes and stationery.
Suspicious, he asked her if she’d been writing to someone.

Knowing her pen pal’s father was her own father’s rival, Hefei didn’t immediately tell the truth. She claimed she’d met a new friend from a neighboring clan.

But Konstantin wasn’t so easily fooled—there were no Silver Dragons bold enough to live next to a Red Flame Dragon, much less befriend them.

Eventually, Hefei’s lie was uncovered. When Konstantin confronted her directly, she admitted she’d been corresponding with Muse, Leon’s daughter, for quite some time.

Surprised, Konstantin asked to see the letters.
