You were currently at the Autobot base as you waited for Ratchet to come out of his berthroom.

"Optimus, when is Ratchet going to come out of his berthroom?" You asked Optimus.

"I am unsure, perhaps you should check on him." Optimus told you.

"Okay." You said as you went to Ratchet's berthroom.

When you were in front of Ratchet's berthroom door you heard music playing......and Ratchet was.....singing?

You couldn't tell what song was playing but when you looked in Ratchet's berthroom you saw him dusting while quietly singing.

You went back to the human area with a smirk on your face.

A few minutes later Ratchet walked into the main room and he saw you smirking.

"Why are you smirking Y/n?" Ratchet asked you.

"Oh, no reason." You said.
