Akk is frustrated with Theo’s carefree attitude after learning why he was at the police station. Akk loses his job, while Theo’s first day at university brings him immediate attention. He’s assigned a mentor named Phupha.

Intrigued by the continued messages from "Enchante" in the book, Theo writes another reply. Learning that the Literature Department is at risk of being shut down, he organizes an event to help save it—with Phupha’s support.

Four university ambassadors all claim to be "Enchante." Believing there’s only one true author, Theo and Akk try to gather handwriting samples from each of them. Meanwhile, preparations for the ZINE fair begin.

Theo is shaken by Phupha’s emotional revelation and ends up arguing with Akk. Just when things seem resolved regarding "Enchante," Natee presents evidence that Phupha isn’t the one behind the messages after all.

After spending a night together in the exhibition room, Theo begins to see Akk differently. Phupha, worried Theo might believe Natee’s lie, becomes desperate to find the real "Enchante." Natee's art club opens its gallery exhibition.

Wayu, after a soccer victory, invites Theo to a celebration. Sensing a hidden agenda, Theo brings Akk along. But he ends up drinking too much. Later, Wayu’s true intentions are revealed.

Only Saifah remains as a possible "Enchante." He invites Theo to see his band perform. Concerned Theo might be hurt again, Akk tries to stop him. But Theo decides to confront Saifah himself.

Theo turns to San for emotional support and advice about his parents. Akk distances himself, but their feelings rekindle when Theo falls ill and Akk cares for him. Still, Theo has something important to confess.
