I saw this one going around, and I didn't quite get it... is it a BDSM thing?

Lol no 😂 This is Princess Bubblegum and Marceline, characters from the cartoon series, Adventure Time. I know nothing of the show, but I see posts about these two a lot that I feel like I know them already haha. They're friendly rivals turned lovers according to Fandom Wiki. Just found this comic of them cute 💕

I noticed the texts aren't readable. The original size is viewable here.
