In the seventh episode of "Had I Not Seen the Sun," Pin-yu and Yun-chen's inquiries for the truth about Hsiao-tung's revelations are abruptly cut short as Hsiao-tung takes over Pin-yu's body. Meanwhile, Ta-wei wakes from a dream where his younger self witnesses a suicide by self-mutilation. He sends a letter to Jen-yao, and she agrees to an interview. As Ta-wei prepares for the meeting, Chien-yi informs him that Ouyang-ti's mother is willing to invest in the documentary on the condition that Ta-wei makes Jen-yao discuss his motive for killing his son.
During the meeting, Jen-yao insists that he will not cooperate, regardless of Ta-wei's decision. If Ta-wei no longer desires to assist, he will find someone else to tell his story. Ta-wei shows him a photo of Hsiao-tung and recounts his interviews with those who knew her. He notes that all the individuals he spoke to had a fondness for Hsiao-tung, with smiles on their faces when discussing her. However, they fell silent when he inquired about what happened to Hsiao-tung later. Ta-wei asserts that he understands better than anyone the significance behind such silence.
One particular aspect that puzzled Ta-wei was when he asked about Hsiao-tung's relationship with Jen-yao; it seemed that no one knew anything about it. Ta-wei reveals that he has seen the video of Hsiao-tung on the internet and suggests that if he were Hsiao-tung's boyfriend, he would not hesitate to take revenge on anyone involved in her ordeal. Jen-yao admits that he knew Hsiao-tung, but they were not close; she was merely the best friend of his girlfriend, Yun-chen.
After returning to the office, Ta-wei encounters Pin-yu, but it is actually Hsiao-tung in Pin-yu's body. Ta-wei suspects that the relationship between Hsiao-tung and Jen-yao was not as straightforward as it seemed, and that Jen-yao was hiding something.
We journey back to the year 2007, where Chang En-ya's envy towards Hsiao-tung reaches its peak, prompting her to lash out at other girls in the dance team. In Taipei, Jen-yao lands a job with a moving company. One evening, a text from his mother beckons him home, informing him that they have returned and settled their debts, freeing him from his hiding.
Jen-yao makes a detour to the school on his way back home. He witnesses Hsiao-tung angrily scrubbing the insults Ouyang-ti and his minions had scrawled on his desk. As he watches Hsiao-tung trash Ouyang-ti's desk and stand up for him, a smile creeps across Jen-yao's face. After their meal, Jen-yao and Hsiao-tung are spotted by Ouyang-ti, but he chooses not to approach them.
Later, Jen-yao visits his old house and finds his mother. He gives her money and urges her to take care of herself, assuring her that he will not be returning and will stay in Taipei. His father hands him the money, saying that they don't need his help and whatever he decides to do next is his own business. Jen-yao and his mother share a meal together, with his mother trying to convince him that his father has changed and even has a new job. However, Jen-yao is uninterested in hearing about him.
Just then, Big K and his gang arrive. They harass Jen-yao's mother by making her drink, but Jen-yao drinks on her behalf and then takes her away. Jen-yao's mother invites him home for a meal, and he agrees.
Meanwhile, Ouyang-ti calls Big K and requests more drugs to be delivered to his secret base since his friends are coming over. It turns out that Big K distributes drugs for Ouyang-ti's father. Big K informs Ouyang-ti that they have taken a break since one of their sellers was arrested. They need to lie low until Ouyang's father resolves the issue and finds a scapegoat. He knows the perfect person to use.
Over dinner at home, Jen-yao's mother tries to convince him to stay, offering to speak with the teachers at school so they can allow Jen-yao to continue his studies until he graduates. However, Jen-yao is resolute. He has no intention of returning to school or staying at home. He informs her that he will be heading to Taipei that night. His father tells his mother that they should just let him go.
Meanwhile, Hsiao-tung admits to Yun-chen over an online chat that she likes Jen-yao. Despite the hurt it may cause, Yun-chen supports Hsiao-tung and encourages her to confess to Jen-yao. The next day, when Jen-yao calls to tell her that he is heading back to Taipei, Hsiao-tung asks him out for a meal before he leaves. They plan to meet at the night market, with Jen-yao picking Hsiao-tung up from around her house.
As Big-K approaches Jen-yao's father, he senses the weight of a tale that is about to be unfolded. He knows that the old man had cheated in a bet in Taipei, using the ill-gotten gains to settle a debt with Big-K. The whispers from Taipei had started to echo, and so Big-K had stepped in to take over the burden. Now, Jen-yao's father owes Big-K a debt that weighs heavily on his conscience.
Big-K's demand for repayment is not merely financial; it is a task that Jen-yao's father must undertake as a means of redemption. The night takes a turn for the worse when the police arrive at their doorstep, their presence ominous and ominous. They sift through Jen-yao's luggage, their eyes scanning for any sign of wrongdoing. And there it is – drugs, a telltale sign of Jen-yao's troubled past.
Panic sets in, and Jen-yao chooses to flee from the authorities. A call from Ouyang-ti comes as a shock – he confesses to setting Jen-yao up in this mess. His father, in a desperate bid for $500,000, had agreed to their plan and sold his son out. Ouyang-ti's motive is simple yet sinister – he hated Jen-yao and wanted to destroy his future. He sought to leave Jen-yao in a state of desperation, with no way out, and to ensure no one would believe him.
In the end, Jen-yao finds solace in Hsiao-tung. He pour out his heart to her, telling her about his father's betrayal and his mother's unwavering disbelief. Hsiao-tung listens silently, her embrace a comforting shield against the storm of his words.
