Oh man, thinking about this show still makes me smile — I watched 'Thirty but Seventeen' during its original run and the dates stuck with me. It aired on SBS from October 24, 2018, to December 13, 2018. The drama was slotted on Wednesdays and Thursdays in the late-night block (around 10:00 PM KST), which felt perfect for winding down after a long day and getting lost in Yeon-woo and Woo-young's awkwardly sweet chemistry.
I used to wait every Wednesday evening for the next episode, texting a friend running commentary like a live commentator — it made the whole viewing feel communal. Beyond the broadcast window, the show’s vibe, the leads’ performances, and the soundtrack kept people revisiting it on streaming platforms afterwards. If you’re hunting for that particular airing context — October to December 2018 on SBS, midweek nights — that’s the original TV timeline. If you missed it back then, it's easy to find now on various streaming services that carry Korean dramas, so you can watch at your own pace and still get the same cozy feeling I did back then.
When I want to give someone a quick timeline, I tell them that 'Thirty but Seventeen' first aired on SBS from October 24, 2018 until December 13, 2018. It was part of the midweek evening lineup, showing on Wednesdays and Thursdays around 10 PM KST, which made it feel like a cozy weekly ritual for viewers tuning in after dinner. I enjoyed how the schedule allowed the story to breathe: two episodes a week kept momentum while giving people time to discuss favorite moments.
If you’re looking the show up now, many streaming services have the series available for catch-up, which is handy if you didn’t catch the original broadcast. Either way, those October-to-December dates are the ones to remember.
I still grin when someone mentions 'Thirty but Seventeen' — for the record, it originally aired on SBS starting October 24, 2018 and wrapped up on December 13, 2018. It ran in the Wednesday–Thursday late evening slot, so episodes came out twice a week. That pacing felt great for a romantic-comedy with a bit of melodrama: not too fast, not too slow.
Watching it live felt like a little midweek treat. The chemistry between the leads made those broadcast nights something to look forward to, and the scheduling helped conversations bubble up online the next day. Even now, when I rewatch clips or the OST, I catch details I missed during the first run. If you’re trying to place the show in a timeline of 2018 K-dramas, think autumn to early winter — perfect season for that warm, slightly melancholic vibe the series has.

Natalie Hale spent five years loving a man who never learned to look at her.
When Ethan Cole's first love returns and he asks for a divorce, Natalie doesn't beg. She doesn't break. She asks for one month, thirty days for him to fulfill every promise he made and never kept. A candlelit dinner, a drive-in movie, an amusement park in autumn, Small things. The things that were supposed to mean us.
He agrees, then he cancels and then he lies. Then she waits alone, again and again, learning in real time what she already knew in her bones, she was never his priority.
But something shifts during that month. He begins to see her: her beauty, her grace, the way a room moves when she enters it. Too late, too slow, and far too little.
On the thirtieth day, Natalie signs the papers, leaves a cup of coffee on the counter made exactly to his taste, and walks out the door.
Three years later, she walks back in not to him, but into the same room. Radiant, accomplished and accompanied by a man who has never once made her wait.
And Ethan Cole finally understands the difference between losing someone and letting them go.
He let her go. She lost nothing.

Arielle never planned to fall in love during her final year of high school. Noah never planned to let his guard down. But when quiet glances turn into late conversations and unspoken feelings surface, they find themselves caught in a connection neither of them is ready to name or walk away from.

As expectations, rumors, and the future press in, Arielle and Noah must decide whether honesty is worth the risk and whether promises made before adulthood can survive what comes after.
Tender, dramatic, and emotionally raw, this story explores what it means to love someone while still learning who you are, and how some promises no matter how small can change the course of a lifetime.

Two different individuals— David Chwe, an 18-year-old boy with secrets darker than a June's night without the guidance of the moon. A boy with phases that are likely to coerce one to kick the bucket.
—
Travis Fujiriki [Park], is a 19-year-old boy who has always isolated himself from the naked eyes of the world.
All that David had to do was to get his mission done and that was to lure Travis into the spider's web but instead, everything chose to travel on a different route.
Sparkles of love began to investigate themselves in the depths of their hearts— once an individual who ran away from affection, Travis was willing to expose his heart to David who became his comfort zone.
Just like in many tales of love and war, the grass is not always greener on the other side.
Will David drop Travis into the lion's den and sacrifice his love? Or will he drop it all and bring him closer under his wing and protect him regardless of anything?
When Henry made a deal with his best friend to make their school's notable Ice Bitch– August, fall in love, he didn't expect that he'd come to respect her instead. And just when he wanted out of the bet, the Ice Bitch found him and made a counter offer. Now with August in his team, the two of them set out an elaborate plan to make their peers believe that the original bet was still in motion. But what started as an easy mission turned complicated when even their own hearts got entangled in very real emotions to what was supposed to be a very fake scheme.
Set in London and Brighton, Thirty Days is a fabulously provocative romance series that gives you a very steamy love affair between a hot guy and an unsure heroine, baked goods and some rather unexpected twists and turns along the way.
Shy and unassuming, Abigail James loves to bake. She dreams of opening her own dessert café but instead she spends her days working as a data analyst and sneaking in her cakes as the company's 'diet assassin' on the side. Taylor Hudson, the enigmatic owner of Hudson International, has been captivated by Abby’s innocence and quiet charm since the day she started working for the company. However, his history with women is marred by personal circumstances and he has vowed to stay away.
A chance meeting sees Abby's world turned upside down when, drawn in by Taylor’s chocolate-coloured eyes and unexpected kindness, she starts on a journey of attraction that will see her heart and soul laid bare. While their attraction is mutual, both Abby and Taylor have their own inner demons that they need to overcome if their relationship can move forward for them to find their own 'happily ever after'.
Wow — such a cozy little drama! If you just want the quick fact: 'Thirty but Seventeen' has 16 episodes in total.
I fell into this one on a rainy weekend and binged most of it because the pacing is so satisfying; each episode runs roughly an hour (some feel closer to 70 minutes), so the 16-episode count gives it enough room to breathe without overstaying its welcome. It’s the kind of rom-com/slice-of-life that builds character moments slowly, so the episode number feels just right for the emotional payoff.
If you’re picking it up, expect gentle humor, a few tearful scenes, and an OST that sneaks up on you — I still hum one of the ballads when doing chores. For a compact K-drama experience that doesn’t drag, 16 episodes is a sweet spot, and 'Thirty but Seventeen' sits comfortably there for me.
