Sunshine Through the Rain ending explained

Spoiler-free verdict

Ending type: Happy ending (HE): the official synopsis says Zheng Yu and Chen Yanzhou win the competition together and admit their feelings.
How painful: Heavy on real-life hardship (debt, a mother in a coma, a brother's death), but the story is about two people pulling each other out of it.
Source: Original script, so there is no novel ending to compare. The page follows the official synopsis until the finale airs.
Episodes out: 16 of 24 in China, per the official schedule

Short answer: a happy ending

The official synopsis says Zheng Yu and Chen Yanzhou win the competition as a team, admit they have feelings for each other, and, supporting each other, climb out of the lowest point of their lives and find a direction for their studies and future.

The drama is still airing (it premiered on November 6, 2026, and the finale date isn't announced). It's an original script, so there is no novel to check against. This page follows the official synopsis and character profiles, and we'll update it after the finale.

What the official synopsis says

In our own words:

Zheng Yu, a top biology student at Qingyi University, is buried in family debt: her father has died, her mother is in a vegetative state and her younger brother lost some of his hearing in a car accident. She works several jobs and needs the Shengji scholarship.
Chen Yanzhou comes from a wealthy family. After his older brother's sudden death he switched to biology to fulfil his brother's wish. He has had heart surgery and took a year off school.
The two start as rivals for the same scholarship, then become partners in a competition.
In the end they win the competition together, confess their feelings and help each other out of their lowest point, each finding a way forward in school and life.

Do Zheng Yu and Chen Yanzhou end up together?

The synopsis says they admit their feelings for each other (互通了彼此心意). It doesn't mention marriage or what happens after graduation, so anything beyond the confession is not confirmed until the finale airs. The character profile says meeting Zheng Yu is what teaches Chen Yanzhou to live for himself instead of for his late brother. Baidu Baike: official character profiles (角色介绍)

What about Chen Yanzhou's health?

His official profile mentions heart surgery and a year off school, and early episodes show a teacher steering him away from football because of it. Nothing in the official material suggests he dies or that the ending turns sad. Baidu Baike: official character profiles (角色介绍) TVmao (电视猫) episode synopses and cast

Where the story is now (spoilers through episode 15)

Rivals to partners. After Zheng Yu helps clear Chen Yanzhou of a false cheating accusation, they enter the Excellence Cup competition as a team.
Each other's secrets. She knows his brother Zhou Guanqi died in a car crash and that his mother has forgotten that son; he knows about her mother, her debts and the uncle who took over her family's home.
A first test. She refuses a judge's 50,000-yuan bribe to quit the competition and exposes him.
Protecting each other. In episodes 9–11, Zheng Yu supports Zhuang Ning against Xie Yudi's bullying. Xie then exposes Zheng Yu's mother's illness and family circumstances at a charity event without consent. Chen interrupts the display and confronts him. Later, Zheng Yu tends Chen's injuries.
Support and recovery. In episode 12, the school expels Xie after the bullying report. Zheng Yu learns his claim to have arranged her mother's hospital bed was false. This is about access to care; her mother waking up is not confirmed.
Living for himself. In episode 13, Chen tells Zheng Yu about his earlier collapse from myocarditis and how his brother's death left him trying to live in his place. His mother's loss of memory is also explained. Zheng Yu defends him from insults, and they join the same research team.
A kiss, not yet a mutual confession. In episodes 14–15, Zheng Yu leaves her convenience-store job to focus on laboratory work. She kisses Chen after drinking. She later acts as though she does not remember it, leaving him hurt and unsure of her feelings.
Still unconfirmed. The full synopses through episode 15 do not establish a mutual confession or a defined relationship, the competition or scholarship result, her mother's recovery, or their graduation plans. TVmao has only short opening extracts for episodes 16–17. Episode 16 is out for SVIP members, while episode 17 is still a preview; neither extract extends this summary beyond episode 15.
