Moon in the Day was something completely unexpected. I started this drama out of pure boredom and honestly didn't expect much from it... But wow, it completely swept me away. I already love a good ghost/possession story, but this one hit differently. I can't even fully describe the emotions it left me with—sad, happy, content... I genuinely don't even know what I'm feeling anymore.
Let's start from the beginning. We're introduced to our female lead, who is, quite frankly, an absolute saint of a firefighter. She literally performs CPR on a dog she rescued from a fire, saves its life, and then takes care of it until the owner is discharged from the hospital. Like... okay, queen, am I supposed to fall in love with you or the male lead?
Then we meet the male lead, who at first is honestly kind of an annoying little menace of a man. Somehow, he's also a famous actor (I guess we really do like them a little dumb sometimes). The two of them meet after a video of her saving the dog goes viral, and he gets cast in an ad related to the fire station. She's brought in to teach him CPR, and they film content together briefly. Naturally, she gets frustrated with him pretty quickly because... well, he's an idiot. And that's basically where everything starts to spiral.
This saint of a woman, Kang Young Hwa, ends up having to protect this man when it turns out someone is trying to kill him. In the process of saving his life, she puts herself in danger—but her guardian spirit steps in to save her and somehow ends up possessing Jun Oh. From there, we find out that Young Hwa and Jun Oh are actually reincarnations tied to a past life from 1500 years ago—her guardian spirit and his wife.
From that point on, the story becomes this intense mix of past and present, with them trying to protect each other and navigate everything that's happening.
Now... Let's talk about the ending. Basically, he saves her, but he's gone afterward. She wishes they'll meet again, and then we get a time skip. We see a younger-looking Young Hwa taking photos of an old building. She trips—and guess who catches her? An even younger-looking Jun Oh, in a school uniform. They lock eyes... and that's it.
And I'm sitting there like—what am I supposed to take from that?? Are we jumping straight into another forbidden love situation? Is she about to fall for a younger guy?? Because she even makes a comment when the first group of students shows up, saying, "Looks like they're here for a school trip. I chose the wrong day," which makes it pretty clear she's not one of them. So... what exactly is the age gap in this new life? Are they just destined to never escape the disapproval surrounding their relationship?
Anyway—questions aside—I really freaking loved this drama. The casting was perfect, and the actors did an incredible job bringing these characters to life. I felt completely immersed in their story and emotions the entire time.
Despite its open-ended conclusion, Moon in the Day delivers a hauntingly beautiful story about love that refuses to fade—even across lifetimes. It's the kind of drama that leaves you with more feelings than answers, and somehow, that's exactly what makes it unforgettable.
So, do I fully understand that ending? No. Am I emotionally attached anyway? Absolutely. Would I go through that rollercoaster again? Also yes. 10/10 would let this drama ruin me one more time.
