@s1m0n4 Yep! In the most recent episode, they did it again, although different, they didn't show any awkwardness or shyness with their flirting and kissing scene. It's as if they're actually dating for years now, they are so comfortable with each other. They should appear together in more shows.
I'm imagining they said to each other, “I'm your girlfriend, you're my boyfriend, let's act naturally.”
