I can't believe I never left a review on this, I'm glad I finally came back to reread it because this is likely one of the best side stories I've seen. Not too many stories really wrap up side characters by giving them their own story, and most of them are never as good as this one. When I realized this story was about Gyerin, I nearly cried! Out of all the characters, she was my favorite and the one most deserving of love in this series. I was so nervous thinking she might end up with Duna so the excitement I felt knowing her ending would be wrapped up in this side story sent me over the moon! Gyerin was honestly the only character in the story who had any real development and personality. Sure, she was clingy, but not nearly as insufferable as the male lead. After reading the main story and both side stories (yeesh on that yaoi side story) Gyerin and Juyeons was really the only relationship I could 100% stand behind that made the most sense to me. I'm so happy she got her good ending, I love how they wrapped up her tale because at the end of the day, she really was the only character (who got hurt) worth caring about.
