Start-Up

Pafhan reunites with her sister Alice after 15 years. Alice appears as a young entrepreneur, accompanied by Rosarin and Jirapat. Pafhan asks Alice if she has ever regretted the path she chose. Jirapat follows Pafhan to the Pancake roll shop, where they meet Boossaba, Pafhan's grandmother who once helped her as a child. Alice asks how Pafhan has been and invites her to a birthday party.

Pafhan searches for Korn mentioned in the letter, and Boossaba, worried, asks Jirapat to help. Jirapat finds Korn and asks him to play the role of "Korn" in the letter. Korn proposes that Jirapat accept the Samkorn Thai Tech into the Sandbox, but Jirapat refuses. Pafhan attends the birthday party, where Alice asks about Korn. Leelawadee is happy to see Pafhan again.

Pafhan asks Korn to pretend to be her boyfriend. Alice asks Korn about his work, and Jirapat quickly says he's about to invest in Korn's company. Leelawadee apologizes to Pafhan for abandoning her 15 years ago. Banthoon assigns Alice to handle work in America, while Withoon takes charge in Thailand. Pafhan, Alice, and the Samkorn Thai Tech apply to join the Sandbox.

At Samkorn Thai Tech, some investors approached them, but Jirapat intervened because they were trying to steal information. Pafhan invited Korn to celebrate a birthday party at the beach, with Jirapat joining as well. When Pafhan and Alice saw Korn coming to the Sandbox, they realized he wasn't actually a businessman. However, Pafhan asked Korn to hire her as the president of Samkorn Thai Tech.

Samkorn Thai Tech develops a program to detect fake and edited images. Alice creates an AI that can quickly manipulate images. Mark lets the Samkorn Thai Tech advance to the next round because he sees Korn's potential and thinks they were given too little time to fix their code. Pafhan wonders why Jirapat has to help them.

Pafhan enters the Sandbox and chooses Jirapat as the team mentor. The team quarrels over dividing the shares, but Pafhan makes a decisive rule to show authority, which Yayha acknowledges, bringing all five members back in harmony. Korn accidentally meets his grandmother at the hospital and learns that she is in the early stages of Parkinson's disease.

Korn proposed using sensors to help the elderly and people with Parkinson's disease. Alice told Pafhan to try contacting Morning Group, but she ended up being tricked into working for free. Pafhan returned to working on the project to help the elderly and people with Parkinson's disease. Grandma asked Pafhan which Korn she liked more from the letters 15 years ago or in the present.

Pafhan searched for companies that invest in CSR initiatives. Korn told her that Grandma was in the early stage of Parkinson's. Pafhan went to Morning Group and found Korn kneeling to apologize for damaging the company's property. She played the audio clip of how they had tricked her and used it as blackmail to make them support True Angel as a CSR project.
