What Happens in Sweet Sixteen: Full Plot Summary

The whole story of Sweet Sixteen (2016) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Xiao Tian and Shu Yawang are close childhood friends. As a high school student, Yawang is asked by her father to tutor Xia Mu, a boy several years younger than her with a traumatizing past who is taken in by her family. Xiao Tian and Yawang grow up together, and Xiao Tian and Yawang fall in love and begin a relationship. Although Yawang comes to see Xia Mu as a younger brother, Xia Mu, who grows into a quiet and brooding teenager, develops feelings for Yawang. Tian enrolls in a military academy and Yawang goes to college, and they eventually get engaged.

Yawang graduates and starts working for a landscape development company, but becomes the target of unwanted romantic attention from Qu Wei Ran, the boss of a company that has connections to Yawang's employer. Xia Mu confesses his feelings for Yawang; she replies that she will always be there for him as his older sister, but her heart belongs to Tian. After a company event, Yawang is drugged and raped by Qu Wei Ran. When Xia Mu finds out about the assault, he goes to Qu Wei Ran's office to confront him. Yawang races there to stop him from doing something rash, arriving just as Xia Mu shoots Qu Wei Ran. She rushes Xia Mu out of the building, and he goes on the run. However, Qu Wei Ran survives the attack, and Yawang discovers that she is pregnant with Qu Wei Ran's child. She agrees to marry Qu Wei Ran if he drops the charges against Xia Mu. Heartbroken, she breaks off all contact with Tian, and her parents urge Tian to move on. When Xia Mu learns about Yawang's pregnancy, he brings her to have an abortion, feeling that he would rather ruin his own life than see Yawang and her child live in misery.

Xia Mu turns himself in and is sentenced to seven years in jail. He is saved from life imprisonment since he willingly confesses his crime. Yawang in turn takes her rape case to court. Qu Wei Ran is found guilty and receives a ten-year prison sentence. Tian asks Yawang to reconsider ending their relationship as his feelings for her have not changed, but she says that they can't go back to the way things were. On a visit to Xia Mu in prison, Yawang tells him that she will wait for him.
