Byeon Wooseok answered a question about how he felt for the kiss scene in (esp. episode 8)
BWS:
"Anyway, even though it was acting, it was exciting because in that scene, we were grownups and I finally knew Sol's feelings.
It was the scene where I ran up the stairs to kiss Sol through all of my overwhelming emotions.
That scene was not just challenging emotionally, but it was also heartwarming when we finally got close to each other and shared a kiss."
"It's the kiss scene with the most NGs."
