IDK why so many people liked this drama. It felt really silly to me. While I understand the reality of a couple grappling with their romance and having other partners in their lives before they find one another, this drama was entirely frustrating and only cute at certain points. I started watching this drama because of the overwhelmingly positive reviews on MDL, but only 2 episodes in I was already bored. I'd have to admit that the drama performed well in certain areas. For one, the music was great! Super cute OST and I love that they didn't restrict themselves to recycling a few sets of songs just because they are written solely for the drama (i.e. they used other music too). I also understand that people like it because it is so down-to-earth and relatable, funny at some parts even. But yes, great acting from the main leads (can't really say the same for the support roles :/) When I finished the drama I just felt like... I listened to my friend tell me her life story about how she got together with her current lover, for example. It just wasn't interesting enough for me. Guess this drama just didn't hit the right spots for me, in terms of plot at least. On a personal preference level, I like my dramas to make me feel like I'm reading a novel; and Marriage, Not Dating made me feel like I'm reading an autobiography. Sorry, not fictional and dramatic enough for me. Whoops. Let me put it this way - if you're out for some great acting and a light filler drama, go for it. Also if you like those that are a little more slice-of-life-ish. But if you're like me and you're looking for dramas that make you choke up and cry, or your heart pound faster in anticipation... then I think you should look somewhere else.
