Opening the final developments of "Stepping into Life", the three sisters Thuong (Quynh Kool) and her grandmother brought gifts to Ms. Hanh's house - Tran Lam's mother (Manh Truong) to thank her for her help over the past time.
Ms. Hanh encouraged the three sisters to try to manage their lives and become more mature so that their grandmother would be less worried.
Meanwhile, Lam still did not forget to tease Thuong with his familiar tone: "You sisters are polite, coming to eat rice is like contributing to a feast. Ms. Thuong should worry less about the younger sisters, worry about getting married sooner".

However, the joy did not last long when Thuong was shocked to hear the news that her close neighbor in her hometown was in critical condition. Lam immediately took everyone back to her hometown. But as soon as they arrived, everyone knew it was just a joke because someone wanted to buy back Thuong's family's land without complicated procedures.
Unexpectedly, the person behind this was Bom - who had bad intentions with Thuong when she used to borrow at high interest rates before. Bom's appearance surprised Thuong.
He did not hesitate to say disrespectful words to her and the three sisters Thuong, and even brazenly said to Thuong: "Do you agree to exchange your house for me?

Witnessing Bom's attitude, Lam immediately stood up to protect Thuong. He recalled that Bom had molested her before and affirmed that if Thuong wanted to sell the house, he would be the buyer, not letting others take advantage of her situation.
After resolving everything, Thuong was grateful for Lam's help and promised to try to repay the debt soon for Lam and her children, and at the same time determined to keep the house left by her parents.
Lam continued to tease Thuong: "Ah, so you decided to be someone else's wife, or are you a little infatuated?" For the first time, Lam frankly admitted that he is not the type of person who likes to help others.
Initially, he helped Thuong for Quan, but later for his own mother: "Looking at her wholeheartedly for her siblings and family, I see my mother's image in it.
The film continues with the image of Thuong and her three siblings encouraging each other to overcome difficulties and determined not to sell the house containing their parents' efforts. Thuong and her siblings play childhood games again in emotional laughter.
From the first steps, grandmother has shown us what love is" Thuong said happily, choked up hugging grandmother.
After all the upheavals, each character has a new journey for themselves. Thuong continues her teaching career with more strength and maturity. Trang grows up, diligently works part-time to help her family.
Giang is also brave enough to divorce, leave her abusive husband and start a new life. Meanwhile, Lam and his mother resolve misunderstandings after a long period of hurt.
At the end of the movie is the meeting between Thuong and Lam: "Stepping into life is not right or wrong, love is also like that. Leaving, moving forward or stopping if you can't forget, why not try to move forward together," Lam said.
At that moment, Quan (Huynh Anh) suddenly reappears. Quan's return closed the film with an open ending, leaving many reflections on youth, love and the journey of maturity of each person.
