Thai superstar Arthit escapes his hectic schedule and finds peace in a hidden Japanese sweets shop, where he meets Sakurako, a woman who set aside her dreams. Their unexpected meeting rekindles paths both had set aside.
Arthit is mistaken for a kidnapper while helping a lost child, but Sakurako steps in just in time. Their reunion is cut short by a huge dango order, and with her father hospitalized, the two team up to save the day.
As Arthit and Sakurako grow closer, a dango delivery leads them to his TV set — forcing him to hide. Meanwhile, Sakurako’s first love, Hayato, suddenly appears at Tokiwa.
Sakurako reunites with her first love, Hayato, stirring old feelings — and Arthit’s jealousy. The next day, Tokiwa thrives thanks to Arthit, but when he's spotted by Richard and Kaede, he runs off into the city.
A double date at an amusement park rekindles sparks between Sakurako and Hayato, leaving Arthit conflicted. Meanwhile, Richard and Kaede close in on Arthit’s location.
After reading a letter from his manager, who tracked down his whereabouts, Arthit is shaken by the trouble he’s caused. As if resolved, he asks Sakurako to show him around Tokyo. The next day, they explore the city by bike, enjoying the sights and finding comfort in each other’s company. But when Arthit unexpectedly runs into Richard in the streets, thoughts of work come rushing back. His brief moment of freedom comes to an end—as a life-changing decision looms ahead.
Holding onto the memories of his time with Sakurako, Arthit returns to reality and successfully attends the stage greeting for his lead film. After hearing from Richard about his future work, Arthit decides with resolve that he will “no longer run away.” Meanwhile, inspired by her encounter with Arthit, Sakurako makes up her mind to pursue her dreams once again and begins studying English. As she spends light-hearted moments with Hayato, the two gradually grow closer.
Sakurako starts dating Hayato, but when her father Toshio pressures her to get married, they end up in an argument. Meanwhile, Arthit continues expanding his career in Japan, working not only on movie events but also commercials. Though he throws himself into work, his smile sometimes fades in unguarded moments. Busy with work, love, and studying English, Sakurako happens to see Arthit on TV and finally discovers his true identity…
Arthit turned out to be a huge star in Thailand! Despite spending so much time together, Sakurako had no idea. Shocked by how different their worlds are, she feels overwhelmed. To cheer her up, Minami suggests they go to an event to see Arthit. While enjoying the event, both girls are filled with mixed emotions as they watch Arthit shine as the “Prince of Smiles.” And then… the long-awaited reunion finally happens.
Sakurako's father safely returns home from the hospital, and daily life at Tokiwa resumes. Though her relationship with Hayato seems to be going well, Sakurako appears distant and preoccupied. When her father hints at marriage with Hayato, Sakurako finds herself emotionally unprepared. Meanwhile, Arthit lands a major job and reaffirms his determination to live as a star. But in an unguarded moment, he comes across a photo of himself with Sakurako—something his manager, Richard, quietly notices...
After arguing with her father and storming out of the house, Sakurako thought she had freed herself from all constraints. However, a single remark from Minami lingers in her heart. Her life, her dreams, her love… As clarity returns, Sakurako begins to truly confront herself. Meanwhile, Arthit finishes his work in Japan and prepares to return to Thailand. During his final interview, memories of his time in Japan flood back, prompting him to speak his true feelings.
Arthit and Sakurako, who met by chance, follow separate paths until a reunion in a foreign land brings them back together. There, they quietly begin to rediscover their feelings for each other.
