It is like, a short sweet unexpected not properly explained mess of two of our favourite characters, I think even the writers were not ready to let go of these characters so they wanted to give us (and themselves more content) that's why they made this.

Overall I just felt like Lee Sang Yi, though a wonderful and talented actor, was not meant for an 18+ character's role. I'm sorry during those flash scenes where he is Kang Hajun I could not take him seriously because he's so cute and always just makes me laugh.

Lee Yoo jin on the other hand was a perfect catch for that type of a role (god help me) his scenes as Kang Hajun were a little too perfect, more than i would like to admit, but damn the whole things was hot, it was very nice though a little underdone but we forgive because the cast was wonderful and the end OST of Lee Sang Yi was so beautiful ❤️❤️
