A life debt, in addition to their first successful mission together, Boba's exceedingly rare promise of loyalty, and the fact that she truly has nowhere else to go, is why Fennec Shand ultimately chooses to stay.
Fennec Shand owes Boba Fett for saving her life, they didn't just bump into each other one day and go, “Whoa, you're a bounty hunter too, that wicked, let's team up!” Fennec is more akin to Boba's indentured servant than his friend, she does as he bids, she doesn't really have a lot of free will.
In a later scene, an unidentified person approaches Fennec's body. Shand returns in the second-season episode "Chapter 14: The Tragedy", in which it is revealed that she was rescued by Boba Fett, who nursed her back to health using cybernetics and recruited her as his partner.
In the end, Fennec contacts a mysterious individual and gives them Hunter and Wrecker's location. It appears Fennec has decided it's monetarily in her favor to betray the batch.
At some point in her youth, Sintas would take up the profession of bounty hunting. It was during her career as a bounty hunter that Sintas would meet fellow bounty hunter, Boba Fett. The two fell in love and were married in 16 BBY, when Sintas was eighteen and Fett sixteen years old.

Did Boba know Vader was Anakin?
In the year 3 ABY, Fett saved Vader's life from an assassination attempt. In the aftermath of the battle, Vader revealed to Fett his true identity: Anakin Skywalker, and his past with the Jedi Order. It was here where Fett learned of the fate of Mace Windu, and how Vader had killed him.
Ailyn Vel was a near-Human bounty hunter, the daughter of Boba Fett and Sintas Vel and the granddaughter of Jango Fett. When Ailyn was just a baby, her father, Boba, was forced to leave her and her mother. By the time she was sixteen, her mother disappeared, leaving her alone.
Fennec Shand was a human female Master Assassin, mercenary, and bounty hunter who worked for many of the top crime syndicates. During the early days of the First Galactic Empire, when Clone Force 99 landed on Pantora, Shand took it upon herself to capture the clone girl Omega who had a bounty placed on her.
Boba Fett was a villain in the original Star Wars trilogy, a cool, stylish, secretive figure only slightly dampened by his ignominious exit from the story, sucked into the belly of a monster while waiting to watch it eat a hero. When he turns up in The Mandalorian, he's just after his father's hand-me-down armor.
Fennec Shand is 16 years older than Boba Fett, but age is largely irrelevant to the two mercenaries, as shown in Star Wars: The Bad Batch and The Mandalorian.
Knowing that he's a foundling explains why Jango wanted a clone for himself; he wanted a foundling of his own to raise, someone to carry on his legacy, as is the Mandalorian way. Mandalorians aren't like many other people.
Though she is older than Boba, she still makes the cut, coming in at around 48 years old. Fennec not only looks good for her age, but shows off what she's learned in her years of experience with some expert sharpshooting, stealth, and hand-to-hand combat.
Fennec Shand was shot by Toro Calican. Calican appeared convinced and holstered his weapon, so Shand approached with her arms outstretched, expecting him to unlock the stuncuffs. Instead, the rookie hunter shot her in the stomach.
After her escape with Clone Force 99, a group of renegade clone commandos, shortly after the formation of the Galactic Empire, the Kaminoans wanted her back so they could create superior clones to keep the Empire's business.
Although he would retain his Mandalorian armor, Prime Minister Almec of the New Mandalorians disavowed any connection to Fett, claiming that he was simply a bounty hunter who had somehow stolen an artifact from Mandalore's troubled past.
Jango hated the Jedi for what they took from him. Perhaps he even hated him for having a home to return to after helping the New Mandalorians take his. Whatever the reason, he hated the Jedi enough to become essential to Palpatine's elaborate plans of genocide.
Is Grogu Yoda? According to the events of "The Mandalorian" so far, Grogu and Yoda are not the same character. They are simply from the same species. The name of this species has never been revealed since "Star Wars" creator George Lucas wanted to give Yoda a sense of mystery.
In the aftermath of the Clone Wars, Fett continued to make a name for himself while working for the Hutt gangster Jabba Desilijic Tiure as well as the Sith Lord Darth Vader. Fett also married Sintas Vel and had a daughter named Ailyn Vel and joined the Journeyman Protectors.
After the death of Jango Fett, Aurra trained Boba Fett as a bounty hunter, teaching him the skills -- and the ruthlessness -- that he would need in pursuing his deadly profession.
