I'm trying to figure out the name of a show, and can only provide a few clues:

Main Female Lead = MFL

1. MFL from poor province and trys to sneak food into palace after being forced in for marriage selections.

2. All of the princes have drawn pictures of each of the girls that where sent to palace for selection.

3. MFL:  sneaks into a kitchen and starts eating food, then a staff member head to kitchen window to grab plates for one of the princes lunch, and MFL puts scraps onto the plates until prince catches on.

4. MFL talks to youngest shy/quiet prince and he likes to draw the different princes.

It’s New Life Begins :) The scenes you’ve mentioned are in episode 1

thank you so much! time to rewatch!
