High EQ (Emotional Quotient) amongst the majority of characters is the highest selling point hence the title Mature Romance, not because of Steamy, half nude sexual scenes. "The Kiss" scene it had, viewers will know what I'm talking about, is WELL WORTH IT, and so aptly built up to that moment. Then characters talk to each other! And avoid all the unnecessary suspense building! Such a novel idea, and saved me so much frustration, man. Even the second male lead isn't blindly in a piss contest with the main one, he too is as emotionally understanding, if not more, than the main.
What I love about the writers wit is, they introduce elements like a side-lead, or the lead's old friend from the US, thus making the viewer anticipate that some miscommunicational drama is about to ensue, so you hold your breath, and you hold your breath, and some more, AND IT RESOLVES! By people talking to each other!

Next let's talk about Fangirling, because it's damn normal, and the drama illustrates how. Armys will definitely love it, and all other KPOP stans as well #weStanStans xD. It also touches upon well-established norms/rules within fandoms, and some touchy issues such as Idols dating. The ugly fanatic reaction to it is shown aptly along with how it impacts people's lives. But it also at the same time highlights what a healthy balance could look like - thus allowing the characters to lead their life normally (without breaking any laws and staying safe)

Last, the ART! and the quotes. There was one episode where they compare FanGirling to Art. The paraphrase '"Why do you stan that artist? You could live happily without them, eat happily without them, further your career without them. Why then? " "Well, because now I've given a piece of my heart to them, I've committed so much time, effort and love to them, how can I stop when I know how much I'll be missing in life?" "Exactly, this is why introducing art to children is important, because humans can be happy, content, and successful without art, but without it something is always missing. and to introduce Art to children is to make their lives more fulfilling, more content, more happy, and to give them a chance to not miss out on it"' - And it's so important! One other notable thought that resonated with me is "There is a word for a woman who loses her husband- Widow, for a man who loses his wife - Widower, for a child who loses their parents - Orphan, but for a parent who loses their child? There is no word, because that pain can not be expressed well with just a word" and I'm not lying I ugly cried. :sob:

All in all, an interesting perspective on Art, life, and relationships that everyone could as well learn a thing or two from. Plus a very calm, soothing, drama. Would recommend for a light hearted, feel good Rom-com.
