In episode 4, the audience easily noticed that the attitude of the children towards Ms. Lam Vy Da had changed significantly. If in previous episodes, she was often "ignored" by students like Bun (Gia Han), MinHee (Minh Hy), now MinHee is allowed to chat and laugh with her. This is a sign that Ms. Da's patience and sophistication have gradually touched the children's emotions.
This volume also marks the appearance of the new trainee teacher "Thanh Duy" in charge of English and Literature - The - American subjects. Mr. Duy had an impressive " entertainment" when transforming into the pink needsle mascot, making the children happy to run to hug and hug them.
However, when the teacher took off his mascot, the atmosphere in the classroom suddenly changed direction. The children immediately became cautious and crowded together because of the "strange person", except for Soc who was still excited. This opens up a big challenge for Mr. Thanh Duy on his journey to build trust in this super-cksulent class.

A prominent situation was when Xe Xe (Baby Chat) burst into tears during meal because she was hurt by her friend Coconut (Viet Dung). Discovering the incident, Ms. Lam Vy Da and Mr. Gin Tuan Kiet immediately approached to reassure both children. Without scolding or rewarding, the two teachers gently explained, helping Xe Xe calm down and letting Duong understand your feelings. When the atmosphere is still tense, they quickly switch to fun activities to make the children forget about the conflict. Mrs. Da also delicately asked Coconut to help Xe Xe prepare a chair, creating an opportunity for the two to " make peace".
Thanks to the right psychological treatment, the classroom quickly became vibrant again. Xie Xe and Duong also coordinated well when participating in the " gray Wolf head" game at the physical park. Also in this activity, Mr. Thanh Duy "laughed and cried" when witnessing the explosive energy of the class. Ms. Da humorously commented: "The 8 children here are as individual as the 80 children outside."
By the second day, the children had made clear progress: more independent when eating, not being "lured" by Wolves with snacks and knowing how to protect themselves. Interesting personalities are also gradually revealed: Strong milk despite being like a doll, Du Du is lovely - easygoing, and MinHee is increasingly close to Miss Da.
