Happy Monday(s) (Sawaddee Wan Jan(s), 2025) Plot Summary and Movie Synopsis:
At the beginning, we meet Earth, a university student overwhelmed by academic pressure and a lingering romantic frustration. Heโs desperate, not just to graduate, but also to express his feelings for Saimai, a girl he secretly admires. Earthโs turning point comes when he witnesses his roommate, Rak, nicknamed Guru for his spiritual quirks, successfully performing a ritual to help someone else. Hoping for similar results, Earth asks Rak to do the ritual for him. But instead of wishing for his own success, Earth wishes for Saimai to get an A. This selfless yet misguided wish shows how deeply he cares for her, prioritizing her happiness over his own.
The ritual comes with a single condition: do not drink alcohol afterward. But Earth, heartbroken by Saimaiโs poor results and jealous of Taeโs romantic performance at the party, loses control. He drinks heavily, violating the ritualโs rule. Earth wakes up the next morning confused; time has reset to the day before. This twist begins a mysterious loop, triggered by his emotional breakdown and reckless disobedience, setting the stage for a journey of self-discovery, second chances, and unintended consequences.
What does Earth do with the Time Loop?
At first, Earth is terrified. When he realizes he is truly reliving the same day, itโs too much to process. His meltdown is intense, and Rak, his roommate, dismisses it as a weed-fueled delusion. Alone in his confusion, Earth tries to make things right, especially with Saimai. For the next several loops, Earth focuses on confessing his feelings. But Saimai keeps friend-zoning him, no matter how differently he approaches her. The constant rejection, despite endless do-overs, chips away at his hope. He begins to question if anything he does will ever change the outcome.
The turning point comes when a scammer casually admits he doesnโt care about consequences. That idea sticks with Earth. If nothing lasts beyond the day, then why worry about right or wrong? Even when he gets shot during a wild night at a gambling den, he wakes up perfectly fine. He now sees the loop not as a curse, but as a power.
With this mindset, Earth starts doing whatever he wants; taking loans, renting luxury cars, and exposing Tae online. He believes that eliminating his rival might impress Saimai. But when nothing works, he turns back to the exam. Earth concludes that the only way Saimai will like him is if she does well. Instead of studying or helping her grow, he manipulates the system. He gets a university staff member drunk and steals the admin password.
What does Earth do for Saimai?
He breaks into the university system using a stolen password and changes her score to a perfect 100. When the results are released, Saimai finally seems impressed. For the first time, she shows real interest in Earth. They celebrate together, and everything appears to be working in his favor. But Earthโs actions arenโt based on honesty or growth, theyโre built on deceit. His affection for Saimai turns into obsession, and his decisions are driven more by desire than genuine care. Just as they are about to kiss at the party, everything crashes. News spreads that Saimai has cheated. Instead of standing by her or taking responsibility, Earth panics. He drinks, assuming heโll wake up to the same day again and reset things.
But the loop is over. Itโs Tuesday. Earth canโt undo anything anymore. Worse, Rak confirms this change. Now the world begins to catch up with his actions. Security footage leaks, showing Earth sneaking into the university dressed in Saimaiโs hoodie. His attempt to help her has only made things worse: public shame, academic dishonor, and broken trust. Earth wants to be the hero in Saimaiโs story, but he never asks what she truly wants. His help turns into harm. What he does for her is really about winning her. In the end, itโs not love, itโs control disguised as care.
Happy Monday(s) (Sawaddee Wan Jan(s), 2025) Movie Ending Explained:
Whatย Consequences does Earth Face for Loitering with the Time Loop?
The time loop is over, and Earth is left to deal with the mess he created. Without the reset button, every selfish action now has a price. The first consequence hits hard: he must repay the massive loan he took to impress Saimai. But he has no money, and reality comes crashing in. When Earth takes Rak to visit Saimai, he finds her dating Tae. The one person he tried so hard to win is now with someone else.
Tae is furious that Earth exposed him online, and the damage canโt be undone. Even Rak turns on Earth. Once a loyal roommate, Rak now calls out Earthโs selfishness. Earth dragged everyone into chaos while chasing a fantasy. Rak even reveals that Earthโs own family is close to bankruptcy, something Earth never cared to notice.
As if emotional fallout isnโt enough, the physical danger becomes real. A violent loan collector shows up, beats Rakโs girlfriend Kimchi, and sends a chilling message: Saimai is next. Earth turns to the police, only to realize that corruption runs deep, and the officer has the same tattoo as the loan collector. Thereโs no help to be found. Tae steps in, surprisingly. He offers to help Earth because Saimai is in danger, and Taeโs father is a senior cop.
But thereโs one condition: Earth must stay away from her. Earth breaks the promise immediately, putting Saimai at risk again. The collector returns, armed and furious. In a desperate move, Earth shoves Saimai into an elevator and leads the chase through the school. A taekwondo student saves him, and the police finally arrest the collector. Earth avoids jail, and the loan is void, but he pays a heavy emotional cost. He loses trust, love, and nearly his life, all because he tried to shortcut his way into someone elseโs heart.
What does Earth do to undo its Mistakes?
Earth finally begins to take responsibility for the damage he has caused. The first step is going home. After learning about his familyโs financial struggles, he visits his parents, not to escape, but to stay. He promises to help his mother with her work and shows a willingness to reconnect with the people who supported him from the start. This marks a turning point in his mindset, from selfish avoidance to active accountability.
At the university farewell party, Earth chooses honesty over image. He goes on stage and confesses to manipulating the exam scores. He also admits how his personal problems hurt those around him. But the audience doesnโt care, they just want music. His emotional confession barely registers, showing that redemption isn’t always dramatic or appreciated. Still, the act is important; itโs for himself, not applause.
Saimai, now leaving for France with Tae, gives Earth a proper goodbye. Earth lashes out immaturely, upset that sheโs choosing her own path. But Saimai stands firm. She calls him out for his aimless life and refuses to be guilted. Their hug and parting words signal closure. Saimai is right to move on, and Earth is left to accept that love canโt be forced or earned through manipulation. Earth returns to clear out his apartment and finds Rak. Despite Earthโs apology, Rak ends the friendship out of respect for Kimchi. Earth understands. He moves back home, where a new billboard signals that things are slowly getting better. Redemption doesnโt mean restoration, but it means growth, and Earth finally starts walking in that direction.
