Chenle, sometimes known as Kael, spends his day as a human often avoiding interacting with others, worried that they would find out his most sacred secret. Whenever Chenle gets overexcited, stressed, or upset he transforms into his dragon form, and it is nearly impossible to control or stop it from happening. In certain situations only his ears or tail will appear.

Chenle is a Fuzanglong dragon which is the dragon of hidden treasures. Chenle is a bit different from most dragons people have heard of, he doesn't hoard gold or gems but instead he hoards sweaters.
