It's also possible that he is a mysterious character who has some sort of connection to Sakura's past or her powers. His presence might trigger something in Sakura, and she can't let him go until she figures out that connection.
One possible reason could be that he has some crucial information that Sakura needs. Maybe he knows secrets about their world or a powerful enemy, and if he escapes, that knowledge will be lost.
Since I haven't read it, I can't be certain, but from the title it seems Sakura and 'him' are likely the main characters. Sakura is the one making the decision to let 'him' escape.
Well, it might be a fan - made story within a particular fandom. Maybe 'him' is a character who has done something wrong but Sakura, for some reason like compassion or a deeper understanding of the situation, decides to let him escape. It could involve elements of adventure, mystery, or even some sort of emotional turmoil depending on the overall context of the fanfiction.
Sakura could be a strong - willed girl, perhaps a talented artist or athlete, who is so dedicated to her craft that she ignores the guy. The guy could be a shy bookworm who has a secret crush on her. He might be the type who is always in the library and is too timid to approach her directly.
'Him' could be a centaur. In the Harry Potter universe, centaurs are intelligent and powerful beings. Harry might ride a centaur in a situation where he needs to quickly cross the forest and the centaur's speed and knowledge of the terrain would be very useful.
There could be prejudice against certain magical creatures. Maybe there are some creatures that are considered dangerous or inferior in the wizarding world. But Harry, in this fanfiction, doesn't go along with that. He takes the time to understand the creatures, like he did with Buckbeak. He doesn't let the general prejudice towards these creatures make him treat them unfairly.
The TV series," Jade Bones," received bad reviews from the audience because of its cliché plot, rustic content, and bad character.

Some people couldn't accept the plot and character design, while others were positive about certain aspects of the drama.
She might be shocked at first. Sakura is used to Naruto being more passive when it comes to her hitting him, so when he suddenly stops her, it could catch her off - guard.
He could use his wandless magic. Harry has shown some ability for wandless magic before. He might use it to unlock the doors or create distractions to escape. For instance, he could make a loud noise to draw the Muggles away from the exit and then make a run for it.
The crew might have seen him as a key figure for their future plans. If he died, their mission or their hopes for a better future might be dashed. So, they saved him to ensure the continuation of their goals. For instance, if he was the only one who knew the location of a valuable resource they needed, they would do everything to keep him alive.
