When Siamwit School faces financial struggles, administrator Paphada decides to merge the Udon Phithak campus with the main campus, Thep Burapha, despite their long-standing rivalry. The students from each campus, who had a long-standing rivalry, found it difficult to coexist. Fights and arguments broke out daily as they struggled to adapt to the new living situation.

Chadjen, a soft-hearted student and president of his own class, found himself falling for a mischievous girl from the Udon Phithak campus. At first, Chadjen had been annoyed by her antics, but as he interacted with her more, he began to develop feelings for her. Even though he knew about the rivalry between the two campuses, he found himself ignoring it, caught up in his attraction to this girl.

Chadjen's friends would warn him about the dangers of becoming involved with someone from the enemy school, but he simply couldn't help himself.
