First let me say, I love Rom-Com and historical parodies... For example: I absolutely adore My Sassy Girl (2017), as the story unfolds you can see the reasoning behind the leads crazy behavior, you also see her grow and mature as she develops a relationship with the lead male... The chemistry they have continues to build as each challenge causes to grow closer. I wish I could say I feel the same about My Only Love Song......I was hopeful with Netflix backing this drama but it lacks true substance, poorly constructed and terribly executed ...I couldn't connect with the lead actress Seung Yeon, no matter how much I wanted to feel for her. I love her in The Circle ..but not here. I don't think it is her fault as much as it could be the script writers or the directors, the chemistry of the actors.... When a drama is well done you can have compassion for the leads even when it's a ROM-COM-Historical parody, you find yourself wanting to see yourself along side them, fighting for them to finish well. Unfortunately, after watching My Only Love Song I can only give it a 5 out 10 rating... There are so many better dramas to invest time in... this is not one I will be watching again. Since I have not seen this mentioned....Side note for parents: This drama is rated for a Mature-14 audience , which is not surprising since most Kdramas are rated for ages 15 and up in Korea. Unlike most k-dramas I have watched in the past.... F@^k and other colorful words are a repeatedly part of the dialog... If you are watching this when younger children who can "read" and they are in the room with you just be aware.
