My Blue Summer (2022) Timeline Explained – Every Event in Order

Luo Zhi's mother kept her distance because Sheng Huainan was the son of the factory owner where her husband died in 1998. The mother was still pursuing compensation money from the factory and felt bitterness toward Sheng's family. She saw any connection to Sheng as incompatible with their family's difficult situation and wanted Luo Zhi to focus on her studies rather than developing feelings for the son of the man she held responsible for her husband's death.

Foreshadowing: This tension is established early when the mother drags Luo Zhi away whenever Sheng Huainan appears, showing the class divide that will haunt their relationship.

• Luo Zhi mother
• Sheng Huainan family
• factory accident
• compensation

Ye Zhanyan, the school beauty who was pursuing Sheng Huainan, stole Luo Zhi's private diary that contained her secret feelings for Sheng. The theft exposed Luo Zhi's hidden emotions to Ye Zhanyan, who then used this information to her advantage. Shortly after stealing the diary, Ye Zhanyan and Sheng Huainan became a couple, effectively crushing Luo Zhi's hopes and forcing her to watch from the sidelines as her private heartbreak played out publicly.

Foreshadowing: The diary's theft marks a turning point that shifts the love triangle decisively against Luo Zhi.

• diary stolen
• Ye Zhanyan
• high school love triangle

Ye Zhanyan was the popular school beauty who openly pursued Sheng Huainan with confidence and directness. After stealing Luo Zhi's diary and learning about her secret feelings, Ye Zhanyan used this knowledge to her advantage. Sheng Huainan, who was unaware of Luo Zhi's long-standing affection, eventually entered into a relationship with Ye Zhanyan. The timing suggests Ye Zhanyan's aggressive pursuit overcame the quieter connection Luo Zhi had maintained through the chalk messages.

Foreshadowing: This relationship forms the core obstacle that prevents Luo Zhi and Sheng from reuniting until university.

• Ye Zhanyan
• Sheng Huainan relationship
• high school romance

By 2012, Luo Zhi is studying law at Xiamen University when she unexpectedly encounters Sheng Huainan, who is involved in a student film project called "Endless Love" directed by Zhang Minrui. Their chance reunion at the university rekindles their childhood connection. Sheng reveals he has broken up with Ye Zhanyan, reopening the possibility of renewed feelings between them. Through collaborating on the film, they gradually rebuild their bond despite years of silence.

Foreshadowing: The film project becomes a catalyst for reconnecting their interrupted childhood story.

• Xiamen reunion
• Endless Love film
• Sheng Huainan director

Luo Zhi left a chalk message on the school wall quoting her favorite film, "Only Yesterday", a Japanese animated film about unrequited love and memory. When Sheng Huainan saw it, he replied with his own message, not knowing who had written the original line. This created a private, anonymous conversation between them that deepened their connection without either fully acknowledging their feelings. The exchange represented their only direct communication during high school, hidden from the social dynamics that otherwise kept them apart.

Foreshadowing: This silent communication foreshadows their later search for the original line and their difficulty expressing feelings openly.

• Only Yesterday film
• chalk message
• secret communication

Multiple factors prevented either from expressing their emotions. Luo Zhi's mother actively discouraged any connection due to the family grievance over compensation. Sheng came from wealth while Luo Zhi felt the weight of their class difference. In high school, Ye Zhanyan's presence and the diary theft added embarrassment and obstacles. Later, as adults, the weight of memories and the fear of rejection kept them silent. Both chose to protect themselves by staying within the safety of their unspoken affection rather than risking the vulnerability of confession.

Foreshadowing: This pattern of silence runs throughout the story, from childhood through their university years.

• unrequited love
• confession
• fear of rejection
• class difference

Only Yesterday serves as a thematic mirror for Luo Zhi and Sheng Huainan's story. It's a Japanese animated film about a woman reflecting on her childhood crush and unresolved feelings. Luo Zhi's favorite scene becomes the source of the chalk message she leaves at school. Sheng Huainan later searches for the original line, treating it as a quest to understand his own past. The film represents their shared nostalgia and the theme of confronting feelings that have lingered from childhood into adulthood.

Foreshadowing: The search for the film quote parallels their own journey of uncovering buried emotions.

• Only Yesterday Takahata Isao
• anime reference
• memory theme

In 1998, when Luo Zhi was eight years old, her father died in a factory accident at the workplace owned by Sheng Huainan's family. This tragedy set the entire trajectory of their relationship in motion. The factory owner (Sheng's father) was responsible for the workplace, and Luo Zhi's mother spent years pursuing compensation for the workers' insurance. This loss created the class divide and family resentment that haunted Luo Zhi and Sheng's connection throughout their lives, making their relationship about more than just romance, it involved guilt, class, and unresolved grief.

Foreshadowing: The accident establishes the central conflict that prevents their relationship from developing naturally.

• factory accident
• father death
• Luo Zhi father
• class divide

In April 2018, Luo Zhi, now a lawyer on a business trip, attends an exhibition honoring Japanese anime director Takahata Isao in Dongshan County. She discovers her long-lost diary among the exhibition items and realizes it contains the detailed record of her teenage secret crush on Sheng Huainan. She requests to reclaim the diary because it documents a love that never fully found its voice. This moment in the present serves as a catalyst for her to finally confront her feelings about the past.

Foreshadowing: The diary's reappearance frames the entire narrative, connecting present to past.

• diary found
• 2018 exhibition
• Takahata Isao
• diary return

The film ends on an ambiguous note, leaving their ultimate fate uncertain. By 2012-2013, they have reconnected at university and grown closer through their collaboration on the film project, yet they still refuse to confess their feelings openly. The weight of their past, family tensions, and the fear of rejection keep them from taking final steps. The 2018 present-day discovery of the diary suggests Luo Zhi is finally ready to confront what happened, but whether they actually reunite is left as an open question, the story poses whether they will find the courage to express what has endured all along.

Foreshadowing: The unresolved ending reflects the central theme: can long-held secret love survive the realities of growing up?
