In the tenth episode of "Had I Not Seen the Sun," we find Hsiao-tung's father, reeling from his failed attempt to run down the boys who had harmed his daughter, now lying in the hospital with minor injuries. Justice for Hsiao-tung eludes them as he tries to make amends with a desperate act of retaliation. Enter Ouyang-ti's mother, capitalizing on the situation to wield her influence over Mrs. Chiang, forcing her into a compromise for compensation. She invites Mrs. Chiang to her home, brandishing the threat of a lawsuit against Mr. Chiang for attempted murder, dangling the carrot of a choice between a typical accident report or a more sinister narrative, complete with an extended stay in prison that could be softened with enough financial sway.
Even after securing Ouyang-ti and his associates behind bars, they boast of their ability to whitewash his past upon release, offering him a new start in the United States with their wealth. Hsiao-tung, on the other hand, is condemned to a life marred by her ordeal, her story forever etched in public memory. The parents, feeling powerless in their daughter's defense, are left to navigate their grief and frustration. They decide to uproot themselves and relocate to Taipei, hoping for a fresh start, unaware that Hsiao-tung's ordeal has already taken its toll online.
In Taipei, Hsiao-tung stumbles upon the video of her incident, circulating on the internet. The comments are rife with vitriol, lashing out not only at her but also at her parents. This avalanche of hatred triggers a mental breakdown for Hsiao-tung, leaving her parents to grapple with the aftermath of their inability to shield their child from the world's cruelty.
Jen-yao's journey to juvenile prison stems from a deeply rooted revenge that consumes him after Hsiao-tung's departure. Big K, an enigmatic figure, visits Jen-yao at his home, offering a glimpse into the Ouyang family's penchant for getting their way and suggesting a timely escape while Ouyang-ti's father is preoccupied with the elections. Despite initial skepticism, Jen-yao's anger and hurt boil over when Hsiao-tung's parents are pushed into a corner and agree to a settlement, relocating to Taipei and promising a five-year reunion.
However, instead of heeding Big K's advice, Jen-yao allows his revenge to fester. The election picture of Ouyang-ti's father, with an amulet around his neck, becomes a chilling clue left by Big K, revealing the latter's true colors. In a fit of rage, Jen-yao sends a letter to the opponent in the upcoming elections and, during the school's grand ballet event, approaches Ouyang-ti in full view of everyone, stabbing him. Though Ouyang-ti survives, Jen-yao is sent to juvenile prison for a few years.
However, the Ouyang family, seeking revenge and seeking to reclaim their lost ground, bribe other inmates to make life difficult for Jen-yao and extend his sentence. Seven years later, in 2014, Jen-yao is released.
The question of whether Jen-yao and Hsiao-tung meet again is a poignant one. As promised, Hsiao-tung waits for Jen-yao on their beloved rooftop during Christmas five years later. Although Jen-yao arrives two years late in January 2014, he finds Christmas decorations, a heartening sign that Hsiao-tung kept her promise. His heartbreak is palpable as he bursts into tears.
Later, on his way home from work at a road construction site, a butterfly leads Jen-yao to a woman he initially mistakes for Hsiao-tung. When she turns around, he realizes she is blind and offers to help her reach her radio station where she hosts a show. As they walk together, Jen-yao learns her name is Hsia Tien-ching. When Tien-ching drops her walking cane and Jen-yao helps her pick it up, he notices a butterfly tattoo on her middle finger—the same as Hsiao-tung's. The simple yet powerful symbol rekindles old memories and feelings within Jen-yao, adding a touch of magic to their potential reunion.
