Bowser isn't bad! I got the idea for this based on this: [link]
If you can't see it, it's a picture of Bowser crying, and the caption reads "You can steal her away in the dead of night. Offer her the sun and the moon and the stars and all the kingdoms below... But try as you might, she will never feel the way you feel for her."
It kind of resonated with me, so I decided to do my own sketch of Bowser looking sad and depressed.
And yes, he's thinking about her.
