I know he's super confident and pretty mature but watching the drama I always felt that was a little bit performative (esp. around his father)

Oh, yes, definitely. I think quite a lot of his confidence is a pose, and a lot of his flirting and teasing is a strategy. I think he's very sure about some things, but his own worth isn't always one of them, you know? *pets him*

So glad this worked for you -- thanks! *chairdances*
