Imagine Frodo Baggins sketching you in secretly. He really has a crush on you and you didn't know.
That is until Sam discovered. But he kept his promise not to tell you.

Sam: what you doing Mr. Frodo?

Frodo: *he hides his sketchbook* n-nothing Sam...just finishing up my Book.

Sam: huh? That almost looked like y/n.

Frodo: n-no..*he chuckles nervously* i-its just a doodle.

Sam: theres nothing to be ashamed Mr. Frodo, I promise I wont tell her/him.

Frodo: oh Sam. Bless you *he hugs him*
