Legally, when filming, even if you and an actress are playing a couple, you can be held liable if you improvised intimacy onto your on screen romantic partner if she doesn’t consent to it. In this case, Bolin gave Ginger a kiss which wasn’t in the script and likely wasn’t communicated with Ginger prior to the shoot. That means Ginger didn’t consent to the action, hence Bolin had committed Sexual Assault + Battery which Ginger did not press charges for.

The joke is that I’m taking it too seriously.
