'Spring of Youth' Lee Seung-hyub Dominates the Finale, Forges Ahead with Debut Amid Misunderstandings with Park Ji-hu
Four Seasons'Spring of Youth' Lee Seung-hyub heated up living rooms across the nation with a jaw-dropping debut ending as the new member of 'The Crown'.

The episode of SBS's youth drama 'Spring of Youth' (written by Kim Min-chul, directed by Kim Sung-yong) aired on the 4th showcased a rollercoaster of despair and hope.

The episode kicked off with Seo Tae-yang (Lee Seung-hyub) secretly signing with Jo&Jo Entertainment and joining 'The Crown' as its new member and leader, just 10 minutes before the comeback song was announced. The comeback song immediately went viral, and upon hearing it, Kim Bom (Park Ji-hu) and Sagye (Ha Yu-jun) suspected plagiarism and headed to Jo&Jo Entertainment.

Despite Sagye's attempts to stop her, an enraged Kim Bom stormed into Jo&Jo Entertainment. She was furious to find out that Georgina (Han Yu-eun) had shamelessly registered the copyright under her own name. This led to Kim Bom's arrest after she swept everything off a desk in anger. Meanwhile, upon discovering Georgina's plagiarism, CEO Jo (Jo Han-chul) heightened the tension by insisting, "That song is yours! You wrote it! So, protect it at all costs. If it gets out... it's over for you, me, and Jo&Jo too!"

At the police station, Sagye tried to calm down an agitated Kim Bom, warning her that a reckless fight against Jo&Jo could lead to being buried by them. He offered his help, but Kim Bom, feeling betrayed by Sagye, coldly turned away.

As Kim Bom and Sagye each sought to expose the plagiarism, Kim Bom was turned down by lawyer Lee Hong-gi, who predicted Jo&Jo would hire a major law firm. Sagye, too, faced setbacks as his posts about Jo&Jo's misdeeds were repeatedly deleted online, and a journalist he approached was warned not to help him.

Meanwhile, Kim Bom, after meeting with Georgina, saw a video of Sagye smashing CEO Jo's car. Georgina blackmailed her into signing a document promising never to raise the issue again in exchange for not releasing the video. Although Kim Bom refused, she was internally worried and declared to an excited Sagye that she would not sue, saying, "I might never be able to sing this song again. Let's stop seeing each other," leaving Sagye stunned. However, Kim Bom later texted Georgina, promising to keep her word about deleting the video, showing her lingering feelings for Sagye.

On the other hand, Seo Tae-yang, unaware of the 'Two Sagye' cover project due to Kim Bom's consideration, mistakenly believed they had moved on without him. His feelings of resentment and jealousy towards Sagye exploded, and he coldly remarked, "Maybe it's for the best. I won't feel sorry for you anymore. It doesn't matter where I start from, right?" before walking away. Later, the 'Two Sagye' members, following Kim Bom's suggestion, filmed their cover song video wearing bucket hats and decided to reveal their faces if the video hit 3 million views by midnight.

In the final scene, as the 'Two Sagye' members anxiously awaited the reveal of 'The Crown's new member at 10 a.m., the countdown ended with Seo Tae-yang's shocking appearance as the new member, leaving everyone frozen in disbelief. The 'shocking debut of Seo Tae-yang' ending has skyrocketed curiosity about what's next.

'Spring of Youth' airs every Wednesday night at 10:40 PM.
