People in the reviews say that Juk Yo is just in love with Eun Gyo and that it shouldn't be wrong because love is love. Juk Yo is in his 70s, and Eun Gyo is a minor. I definitely agree with Ji Woo when he mentioned how wrong it is for the two to be together. Juk Yo does love her, undoubtedly, but unlike what many say, he's not content with her just being there with him.
On many occasions does he fantasize about touching her which eventually led to him writing that poem. And every time he was about to touch her inappropriately, he held back because he was AWARE that what he was doing is wrong. He has the right to love her, which still doesn't sit right with me but it's a fact, but fantasizing about a minor is too much. I would be okay with it if he really was just happy with her being around him, but that obviously wasn't the case. It left me feeling gross.

Other than the romance aspect of the story, I liked the relationship between Ji Woo and Juk Yo, and how complicated it is. The acting is superb but the music isn't that memorable (I do believe that it fitted the scenes well though). I doubt I'll ever watch this again. Everyone has their own definition and boundaries for love, and this just isn't it for me.
