Guess who's been rewatch Snowdrop ep 16, especially the parting scene? ME!
It's beautiful (not the shooting part). Sooho and Youngro love story was always beautiful and pure.
Sooho, who protects his love one, already put Youngro's safety first from the first day they met. He didn't continue to ask her out coz he saw Gyeokchan eyeing them. He's worried Gyeokchan would do anything dangerous to her.
Youngro, who bright selfless kindhearted, already willing to be on Sooho's side from their first encounter. She didn't continue her group date but brave enough to ask Sooho to meet her again next day. She, again, instantly forgive him and helping him when he's hurt and being chased by ANSP, even she didn't hear a word from him for months after that unsuccessful date.
I think Sooho will be living in agony even if he's successfully saving his sister and escaped outside NK. Him knowing Youngro died with her last memory that Sooho didn't love her back.
That's why I am satisfied with how their love story unfold. Even though they parted eternally, they know that they love each other. Sooho protects her until his last breath. Youngro was there with him until his last. And she lived, like Sooho told her to, because he knew that she would. Because Youngro like a Snowdrop, a flower that blooms in the snow.
