Is this possibly the beginning of something else? Often times, changing appearances is the start of a new chapter of their life that has (or yet to) come. We've seen dark haired Sangwoo from flashbacks, which was from a much more vulnerable time in his life. So I assume he associates it with being weaker, thus why he dyed this hair after the death of his parents, which I'm guessing was some sort of Baptism. Throughout the series, we slowly witnessed his hair changing. Just subtle things here and there like, It's gotten longer, it sits on his face a little differently and the roots have started growing out. Perhaps this was supposed to signify his slow but inevitable progress towards Bum, his needs and feelings. Maybe now that it's all long and straight, he will start making bigger changes with more impactful consequences. Thoughts?
