NCT's Jaehyun leaves a cute selfie to prove he ate his first kumquat.

NCT's Jaehyun posted a mirror selfie taken in the practice room on Instagram!

When revealing this photo at the fan concert, they also revealed for the first time that they are growing a kumquat tree.

I uploaded the original photo on Instagram haha

Seriously, isn't the selfie proving she's holding kumquats just too cute? lol
