Flawed Emblem #1: She's too Young

Hayato trying to prove he's mature by being immature. Hinoka doesn't seem to take his joke lightly.

The first (completed at least) comic of a series of incoming ones centering around FE (whether it'll just be Fates or not is still in the air). I actually took a few hours to draw out a bad joke. I'll improve in due time I swear. To be honest, I never actually heard of that phrase until one of EWNetwork's streams when the video buffered. It was in the chat for like a second and I decided to test it out this way.

Also, bonus points if you know why I chose the quote "You're not ready for this!" at the end.

I'm so sorry if the quality of the picture itself is a piece of trash. Must be the way I uploaded here from the Wii U.
UPDATE: Kinda fixed a few things for more polish. Also will the picture not turn out so blurry pls.
