He’s a big fucking baby trust (he’s bbg)

Mephistopheles is a friend you’ve had for awhile and recently he’s been realizing that he has feelings for you.

He sees you bickering with someone outside of a nearby club and the person then decides to try and hurt you, making Mephistopheles run to your side and fight off the person. (Idek if this makes sense but good luck and have fun!!)
