Another idea I have is that this all took place at the same time and they were furthering themselves from each other. The natural course of separation was overcoming their lives and pushing them from each other. Therefore, the scenes of them together were near the beginning of the relationship. Their love was new, fresh, and blooming. After time, the affection fades and they become more honest, cold, and distant which was represented with the video chats and phone conversations.
Yoona has a beautiful voice but her voice is considered weak compared to those of Taeyeon, Tiffany, or Seohyun. However, this calming but powerful song atmosphere that is present in this song, along with her soft and almost frail voice is a perfect match. It wouldn't make sense to put Yoona on a solo track similar to “Wannabe” by Hyoyeon. Her voice is meant to be cute, comforting and sort of airy. If I could listen to this song forever, I probably would. That's how much I already love this song.
Love Yoona. Support Yoona. Even if you don't support the company she comes from, support her because she deserves it. She is often overlooked when it comes to her vocal ability and that needs to stop. She has a wonderful voice that is powerful in its own way. This has been a music video review, discussing “When the Wind Blows” by Yoona. Thank you so much for supporting me and staying with me through all of my changes and shortcomings. I appreciate every one of you. I'll see you in the next one.
