Thank You Teacher

Goh, survives a bus accident during a field trip thanks to the heroic act of a teacher, who was her homeroom teacher in M.3. Teacher Chaichana was not fully recognized as a teacher simply because he was a contract teacher, yet he sacrificed his life, causing immense pain to Supha, his wife. This incident sparked Goh's desire to become a teacher, despite Supha's disagreement. Eventually, as time passed, Goh grew up, graduated from the Faculty of Education, and spent several years trying to pass the civil service exam to become a permanent teacher. Finally, Goh was selected and interviewed to become a contract Thai language teacher at Phatham School. Upon joining as a contract teacher, she had to face many challenges, including rumors of favoritism because her aunt worked at the same school.

Goh is accused of getting the job unfairly due to favoritism from the school administration. However, Goh fights back and tries to prove herself as a good teacher. Goh is assigned to the guidance department, led by Teacher Rubkwan, who doesn't like her much, believing she's a favorite. There's also Teacher Tarwin, a TV teacher Goh admires, and Teacher Pon, who secretly supports Goh. In her early days as a teacher, Goh had to overcome many challenges: prejudiced fellow teachers, students who don't understand her teaching methods, and Teacher Pawinee, the head of the Thai language department, who exploits her by constantly forcing Goh to create teaching materials. Through facing these challenges at school, Teacher Rubkwan gradually starts to see her in a better light.

Goh's persistent efforts in creating engaging teaching materials slowly open old-school Pawinee's mind to new teaching methods. Despite the heavy workload and time management challenges, Goh's dedication makes the school's Open House a resounding success, bringing renewed attention to Phatham School. However, her triumph is shadowed by intensifying rumors about her "connections."

Goh's faces a new challenge: her contract is renewed for only six months. Devastated, Goh considers giving up, but Rubkwan encourages her to persevere for the students. Goh returns to school with renewed determination, despite the short contract. The guidance department, led by Rubkwan, is responsible for an upcoming "Guidance Relations" event. Meanwhile, teacher Yong, Goh's rival, is also assigned to give the school's guidance speech at the event. During the event, teacher Yong is heavily criticized by parents. Rubkwan steps in to manage the situation and uses the brochure Goh created, which mentions a quota from Salaya University, to salvage the event. This, however, leads to a major problem as Phatham School has never actually received an offer for a quota from Salaya University.

The guidance department presents a Salaya University quota at the "Guidance Relations" event, despite it not actually existing. This puts immense pressure on Rubkwan, who is tasked by the principal and Assistant Principal Mongkol to secure the quota as promised. They try desperately to contact Salaya University, but receive no response. They decide to visit the university in person and encounter Assistant Professor Worawan. Meanwhile, the principal, realizing that the guidance department may not be able to secure the Salaya quota, prepares a backup plan.

The principal and administration approve the opening of a gifted program, but selecting a homeroom teacher proves challenging. Teacher Yong volunteers, aiming to impress the executives. Meanwhile, Rubkwan intensely pressures herself to secure the Salaya University quota. Student selection for the gifted program proceeds quickly. Tae and Nicha are highly motivated to be chosen. Teacher Juad also decorates the gifted classroom luxuriously, making other students envious. Meanwhile, Teacher Sumeth, investigating who posted attacks on the school, finds crucial evidence.
