Can someone explain to me what the fuck just happened?

Tbh I don't know either but basically the director and that actor have a sexual relationship going on, they've known each other for a while, and most likely the actor uses it as a 'play' as if he is acting before a camera. Blonde boy is probably gonna be hooked into this shit by that actor and ya know, smut stuff, drama, etc. the usual with triangles

Thank you for the summary, greatly appreciated! ヾ(☆▽☆)
