The final round draws near but the band faces challenge after challenge including injuries, misunderstandings and the loss of their rehearsal space. At the same time Nut quietly hides signs that his health may not let him reach the stage he has waited for his whole life.

Win sets out to reunite the band with Chai and Ek as his key targets. It is not easy but he pushes forward, determined to bring everything back. Yet even the smallest changes begin to cause ripple effects he never expected.

Win, a 44-year-old aimless office worker, is transported back to his 17-year-old self, reuniting with his late best friend Nut.

When Win decides to confess his feelings to Nut, things don't go as he expected. Just a few words set off a chain reaction and what was supposed to be the beginning of their band might fall apart before it even begins.

After reaching the final round the band spends time together in a warm and lively camping atmosphere. Win tries to complete everything left in his heart one step at a time but some feelings are still too hard to say. Meanwhile their relationships begin to shift without anyone realizing it.

Lin's return makes Win hesitate about the path he's chosen. As someone important from the past shifts the balance of everything Win has built he begins to wonder who he is really trying to change the past for.

As Win starts seeing the results of what he's tried to change, some parts of the past seem to fall into place but not everything turns out as hoped. The bonds he relied on begin to weaken and he realizes that going back in time does not mean he can control how things turn out.

Win becomes haunted by guilt from the past while the bonds within the band begin to shake without warning. As hidden truths slowly come to light everything he tried to protect starts to collapse before his eyes.
