Im Joongwon's OST Has 'Perfect Crown' Fans in Tears

A single piano melody was all it took. When Im Joongwon's voice began to fill the screen during one of Perfect Crown's most devastating scenes, viewers across the country reached for their tissues — and didn't stop. The OST Part.10 track "Am I Wrong to Love This Way?" (사랑하는 법이 틀렸나요), released on May 9, 2026, is now being called one of the most emotionally resonant songs in the drama's acclaimed soundtrack lineup.

Featured on the official 1theK YouTube channel, the music video for Im Joongwon's ballad has already racked up significant views, with fans flooding the comments section to share the exact moment the song broke them. The song marks Im Joongwon's first major OST contribution, and it arrives at a pivotal moment in both his career and the drama's storyline.

A Song Written From the Heart, For the Hardest Scenes

"Am I Wrong to Love This Way?" is not a song that was handed to Im Joongwon to perform. He wrote it, composed it, and sang it — a deeply personal creative investment that shows in every note. The ballad centers on a simple but devastating piano melody, layered with vintage-textured guitar and softly swelling strings that give the track a warm, restrained quality. Im Joongwon's controlled vocal delivery doesn't demand attention so much as it earns it, building emotion slowly and deliberately until the weight of it becomes undeniable.

The production team behind Perfect Crown placed this song in precisely the right moments. In Episode 8, the track plays over two of the drama's most talked-about sequences: the scene where Seong Hee-ju (played by IU), after collapsing during a wedding ceremony, dramatically revives and is caught in an emotional embrace with Lee An-daegun (Byeon Woo-seok); and the episode's closing shot, where Lee An-daegun shields Seong Hee-ju from a swarm of press reporters, his body language saying everything the script doesn't need to.

The song returned in Episode 9 with even greater effect. As suspicion and accusations mount against the royal couple, Seong Hee-ju makes the gut-wrenching decision to protect her husband by telling him, "Let's get divorced" — and the ballad swells beneath her words, amplifying the sacrifice in a way that words alone never could. For many viewers, that scene has become the defining moment of the series so far.

Who Is Im Joongwon? The Indie Voice Behind the OST

Im Joongwon serves as the frontman of Sonlmor (손을모아), an indie band that has built a devoted following within South Korea's independent music scene. The group is known for a rock-influenced sound that leans into raw, emotionally direct songwriting — qualities that might seem at odds with a drama ballad, but which make Im Joongwon's approach to "Am I Wrong to Love This Way?" all the more interesting.

Rather than simply delivering someone else's composition, Im Joongwon used the OST opportunity to flex a different creative muscle. Where his work with Sonlmor often trades in intensity and sonic texture, this ballad strips everything back. The result is a song that feels simultaneously unlike his usual output and entirely consistent with what makes him a compelling artist — the ability to make listeners feel something without overselling the emotion.

Kakao Entertainment, which is distributing the Perfect Crown OST, described Im Joongwon's contribution as capturing "the delicate emotional thread between two people who refuse to let go of each other, even in the most desperate moments." That description tracks: there is a sense of stubborn, quiet love in every measure of the song, mirroring the central dynamic between Seong Hee-ju and Lee An-daegun.

Perfect Crown's Record-Breaking Run

Perfect Crown (21세기 대군부인) is a MBC Friday-Saturday drama set in a fictional version of present-day South Korea operating under a constitutional monarchy. The premise — a modern woman navigating royal life, class expectations, and a politically complicated marriage — has struck a chord with audiences both domestically and internationally.

The drama has held the top spot in its time slot for domestic ratings, outperforming every competing broadcast. On the streaming side, it has claimed the #1 position in Disney+'s Top 10 TV Shows (Non-English, Global), a milestone that places it among the most-watched Korean dramas on the platform at any given moment. The combination of IU's star power, Byeon Woo-seok's rising profile following his breakout in Lovely Runner, and a script that balances political intrigue with deeply felt romance has made Perfect Crown one of the most talked-about dramas of 2026.

The OST lineup has been widely praised as one of the show's underrated strengths. With each new release, the soundtrack has expanded the emotional vocabulary of the drama, giving audiences something to hold onto between episodes. Im Joongwon's entry into that lineup arrives at exactly the right time — as the narrative stakes hit their peak and the central relationship faces its greatest test.

Fan Reaction: The Scene and the Song

Social media responses to "Am I Wrong to Love This Way?" have been immediate and consistent in their intensity. Fans who had already been rewatching the Episode 8 and 9 scenes in question now have a song to attach to the emotions those moments stirred. Comments across YouTube, Twitter, and fan communities have ranged from simple expressions of grief ("I wasn't prepared") to more detailed analyses of why the pairing of Im Joongwon's restrained delivery with the drama's most heartbreaking beats works so effectively.

Several fans noted that the song's title itself — "Am I Wrong to Love This Way?" — functions almost as a question Seong Hee-ju asks herself in that pivotal Episode 9 ending, adding a layer of meaning that feels intentional rather than coincidental. Whether or not that was the creative intent, it's the kind of detail that turns a good OST into a cultural moment.

What Comes Next

"Am I Wrong to Love This Way?" is available now on all major music streaming platforms. Perfect Crown Episode 10 aired on May 9, 2026, continuing what has become the most riveting stretch of episodes in the drama's run. With the plot tightening and the central couple under increasing pressure, the likelihood that this song will return — and hit even harder the second time — seems very high.

For Im Joongwon, this OST marks a meaningful expansion of his creative profile. The transition from indie rock frontman to drama ballad composer and performer is not a common one, and "Am I Wrong to Love This Way?" suggests he has the range to make it work on his own terms. It will be worth watching where he takes this momentum next.
