If the whole point was to feel "finally" as Sejin took his own life... Then they succeeded in showing it to us. It was so emotionally exhausting that I think all of us were just waiting for it to end. That's how "show not tell" is done.
I feel like everyone congratulating them are also thinking "about time" lol and also iirc everyone knows how much Seol Cheonyu likes the prince, it's just that I think this is the first time prince showed he accepts Ahseol's feelings
Love them freak4freak hahaha
