Hahaha I feel like Gojo and Getto should be the endgame last battle, since Sukuna really is someone for Yuji to defeat since he was the vessel, and Geto was Gojo's responsibility since he failed to look out for it causing to be stolen. Wahaha just want kenjaku to fight gojo however he's well aware he stood no chance to gojo based on shibuya incident and chose to seal him instead.
I think Siyun's messing with her, this is his way of making FL leave her Job (where there was a younger co-worker) He would've probably drop the 19+ drama in exchange of Jeongmin resigning on the coffee shop
