The episode begins with a coincidental bond between Thuong (Quynh Kool) and Mrs. Hanh (NSND Lan Huong). Seeing the principal waiting for the bus after buying fermented pork roll, Thuong proactively takes the boss home by motorbike and invites her to enjoy sticky rice by the roadside.
Looking at the photos of the two close people, Trang (Ngoc Thuy) immediately came up with the idea of associating her older sister with her boss's son Lam (Manh Truong). She pretended to stumble and twist her leg, using the reason of a set of important documents to force Thuong to deliver it directly to Lam.

As soon as she disappeared from her sister's face, Trang immediately walked around normally and was exposed by her youngest brother Minh. Being exposed, Trang calmly admitted that she was creating an opportunity for Ms. Thuong to soon forget her old love: "Since Mr. Quan broke up with Mrs. Thuong, coming back to hide from my mother's skirt, I hate it. All my life I'm just a mama boy".
When receiving the document, Lam easily saw through Trang's tricks. He mocked and advised Thuong to get back to Quan: "That Quan is suffering a lot... young couple falling in love again, youth is very short".
However, Thuong resolutely refused. Seeing the package of fermented pork roll that Lam was carrying, she recalled the coincidence this morning and reminded him: "Human life is short, sometimes you can't even love you, try to treat your mother well.
To prepare for the death anniversary of Lam's grandmother, Thuong proactively made a pot of sticky rice cake from his hometown and brought it to Hanh's grandmother. Younger brother Minh joked with his sister: "It turns out that my grandmother's whole career also depends on this pot of sticky rice cake". Thuong immediately brushed it aside: "I don't intend to beg for anything. This is my heart. What I make myself is more meaningful".

Meanwhile, Trang was struggling to find a way to approach Professor Sach, she immediately seized the opportunity to ask her for a few to take and conquer the demanding expert. Thanks to skillfully recalling the article full of nostalgia about Professor Sach's late mother and the country cake, Trang succeeded, making him heartbroken.
At the company, she also received good news when the script was approved and officially retained as a collaborator, although she herself was quite confused when she learned that Dung suddenly applied for leave.
The film's plot continues when Thuong brings banh khuc to Mrs. Hanh's house. The atmosphere subsides when Mrs. Hanh stands in front of the altar and sheds tears, choking up and confiding: "She has been away from me for 23 years and has never returned here. But I still hope she will understand, she will forgive me, Mom".
Right at the moment of despair, Lam suddenly appeared in front of the gate. Thanks to Thuong's advice this morning, he temporarily put aside his coldness to step in and burn incense. Mrs. Hanh burst into happiness.
Seeing the family reunited, Thuong asked for permission to leave, but Ms. Hanh held her hand and kept her because she wanted someone to dispel the shy atmosphere. The meal was warm when Ms. Hanh personally wrapped the fermented pork roll and took chili sauce for Lam.
Seeing that Thuong was liked by his mother, Lam teased: "It's not enough to flatter the boss, but you still intend to flatter the boss's son". Thuong immediately retorted: "Then I will have the opportunity to serve you, or do you want me to feed you something, okay?
The scene closes with Lam wondering why his grandmother always blames herself. Mrs. Hanh sadly explained: "Grandmother is always tormented just because she is sick and we have to be separated.
Will the truth about the past help Lam completely forgive his mother, and how will Trang manage when entering the official working journey? Let's look forward to the next exciting details of Step into Life.
