Episode 3 of "Head Over Heels" kicks off with Sung-ah steadfastly perched outside the funeral parlor housing Gyeon-woo's grandmother, where she bears witness to Gyeon-woo being ostracized by his extended family. Ultimately, he is compelled to depart as whispers of his parents' impending arrival ripple through the crowd.
Meanwhile, Sung-ah's spiritual mother, General Dongcheon, leads her fellow shamans in a ritual to purge a haunted abode of malevolent entities. Amidst the ceremony, they confront a lethal curse that strikes General Dongcheon as she shields her comrades. She promptly seals the house, disclosing that the malevolent spirit within possesses a strength that defies conventional exorcism. Subsequent investigations unveil that a human sacrifice had empowered this spirit, fueling its unprecedented might.
Elsewhere, Gyeon-woo's solitude deepens following his grandmother's demise, to the extent that Sung-ah discovers him ensnared by the influence of a suicidal apparition. Desperate to save him, Sung-ah seeks assistance from her spiritual mother. General Dongcheon reveals that Gyeon-woo's desire to live holds the key to his salvation. Alternatively, Sung-ah could become a human talisman; every touch she bestows upon him will repel the suicidal spirit.
Starting the next day, Sung-ah, now transformed into a human talisman, employs every conceivable, albeit humorous, means to touch Gyeon-woo. Concurrently, their classmates uncover the truth about Gyeon-woo's innocence in the school storage room fire after eavesdropping on the archery coach defending him.
As Sung-ah's antics unfold, the stakes rise, entangling them in a web of supernatural and human drama that promises to test their resolve and forge unexpected alliances.
After school bell rang, Sung-ah covertly tailed Gyeon-woo, only to be eventually discovered. Together, they ventured to the columbarium to pay tribute, placing photos of Gyeon-woo alongside his beloved grandmother. Upon witnessing the snapshots, Sung-ah's eyes welled up with tears, noticing the radiant joy that beamed from his grandmother's face when Gyeon-woo claimed the gold medal in archery. At this realization, the haunting specter of suicide began to recede.
Later that day, Gyeon-woo mustered the courage to return to the archery field for the first time since his abrupt departure, with his coach discreetly observing him from a distance, silent yet supportive.
The following day at school, amidst a bustling group project, Sung-ah's keen eyes detected a baby ghost clinging to one of her classmates. Her thoughts drifted back to her spiritual mother's solemn warning about three elusive ghost types: the smiling, the dancing, and the baby ghosts—entities too intricate to console like other spectral beings.
With renewed resolve, the coach exhorted Gyeon-woo to reconsider his archery career, suggesting even a ceremonial farewell might bring closure. As Gyeon-woo resumed his practice with renewed vigor, the specter of suicide continued to diminish into the ether.
Elsewhere, Sung-ah crafted another protective amulet, specifically designed to shield Gyeon-woo from the ominous baby ghost. The next morning, she stealthily slipped it beneath his desk. Their paths unexpectedly crossed, leading to a heartfelt conversation about Gyeon-woo's unwavering passion for archery. During this intimate exchange, Gyeon-woo found himself inexplicably drawn to Sung-ah's radiant optimism and unwavering determination. This poignant moment marked the suicide ghost's final disappearance, leaving no trace behind.
In the episode's culminating scene, Sung-ah, attempting to celebrate with a high five, accidentally intertwined her fingers with Gyeon-woo's. He, too, grasped back warmly, sealing the moment with an unexpected touch of camaraderie and perhaps something more, bringing the episode to a heartwarming close.
