At the engineering faculty where Kongpob has enrolled, the traditional freshman initiation is in full swing. Kongpob speaks out against the unreasonable instructions from third-year seniors, including Arthit. However, a secret gets exposed and Kongpob is punished.

More freshmen begin fleeing the harsh training. The third-years worry about their current methods. One day in the cheer room, Prem emotionally lashes out at Ward, a freshman who failed to greet them, and ends up kicking him out.

The second-years are collectively punished by the third-year seniors. Kongpob is told to leave by Arthit. Meanwhile, Kongpob learns the real reason why Arthit was removed as the leader of the training team.

The cheer room activities are temporarily suspended. However, the freshmen must still participate in a university sports competition. Under pressure to win for the pride of the engineering faculty, Kongpob boldly declares, “We will win.”

Right after the victory, Kongpob hurries to the Star & Moon Contest venue and makes it to the finals with Praepailin. Asked by the judges about the current SOTUS system, Kongpob speaks candidly.

Learning that Arthit is still running late into the night, Kongpob rushes to stop him. The next day, Arthit is so exhausted he can’t move. When Kongpob comes to care for him, Arthit is flustered by the attention...

Arthit finds out that Kongpob originally wanted to major in economics and reacts coldly. Meanwhile, the freshmen face their final “flag challenge,” with five senior trainers standing in their way, telling them to earn it on their own.

Having successfully completed the flag challenge, the freshmen receive wrist charms from their seniors to wish them success in studies, love, and student life. Meanwhile, the administration finally grants permission for the Lap Norn camp after intense negotiation.

With Lap Norn completed, Kongpob and Arthit share a calm moment by the shoreline. Kongpob gives Arthit a symbolic gear he worked hard to earn, asking him to keep it—leaving Arthit visibly shaken.

After shopping, Arthit returns to find his dorm room flooded. With no other choice, he stays in Kongpob’s room, where he realizes he can see his own room from there...

In high school, Arthit liked Namtaan but gave up without confessing, letting his friend Jay have a chance. One day, Namtaan confides in Arthit that her relationship with Jay isn’t going well.

Kongpob is discouraged by Arthit’s coldness. Arthit confides in his friend Knot that a junior has confessed to him. Meanwhile, Em asks Kongpob what he would do if someone he didn’t like confessed to him.

On the day of seniors Tam and Fon’s wedding, Kongpob—hesitant to face Arthit—goes to the venue. Arthit tries to talk to him, but Kongpob keeps his distance.

As freshmen, Arthit, Knot, Bright, and Poom also endured strict SOTUS training from seniors like Tam. Now it's Kongpob’s turn to become Head Gear. One day, Arthit returns to the university as a working adult.
