In some fanfictions, Sasuke could yell at Sakura if she accidentally endangers their mission. For example, if she makes a mistake that puts the whole team at risk, his anger might lead to him yelling at her. Also, if Sakura tries to change Sasuke's mindset about his goals in a way he doesn't like, he may lash out verbally.
One possible reason could be that Sasuke is frustrated with Sakura constantly trying to get close to him when he's focused on his revenge. He might yell at her to keep her away and not interfere with his plans.
One possible reason could be Sakura's constant pining for Sasuke. Naruto might feel frustrated that she's so focused on Sasuke when he's right there for her. In the Naruto universe, Naruto has always been a bit jealous of Sakura's love for Sasuke, and in fanfiction, this could be amplified to the point where he yells at her out of pent - up emotions.
One possible reason could be Sasuke's continuous absence. He is often away on missions, leaving Sakura feeling lonely and neglected. In fanfiction, this could be exaggerated to a point where she can't take it anymore.
In some fanfictions, Sasuke could be under the influence of some dark power or curse. This power might compel him to kidnap Sakura. For example, a dark entity might want to use Sakura's abilities or her connection to Sasuke for its own evil purposes, and Sasuke, being unable to fully control himself, follows its commands.
One possible reason could be Sasuke's pursuit of power. In many fanfictions, his thirst for greater strength might lead him to leave Sakura behind as he embarks on a solo journey to train in more dangerous and secluded places. He may feel that his goals are too dangerous for her to be involved with.
One possible reason could be a lack of communication. If Sasuke is always away on his missions and doesn't share his thoughts and feelings with Sakura, it can create a rift. Another reason might be differences in their long - term goals. For example, Sakura may want a more stable family life, while Sasuke is still too focused on his pursuit of power or justice in the shinobi world.
One possible reason could be their different life goals. Sasuke has always been on a journey of self - discovery and revenge in a way. Sakura, on the other hand, is more focused on building a family and a stable life. In the fanfiction, this clash of ideals might lead to their divorce. For example, Sasuke might feel that his pursuit of power or understanding his clan's past still takes precedence over his family life with Sakura.
In fanfiction, Sasuke might snap at Sakura due to miscommunication. Sakura could be expressing her concern for him in a way that he misinterprets. For instance, if she tells him not to go on a dangerous mission and he thinks she is trying to control him instead of just caring about his safety. Another factor could be the influence of external forces. Maybe there are other characters or events that put him in a bad mood, and Sakura just happens to be there at the wrong time, so he snaps at her.
One reason could be to seek a new life away from the constraints of Konoha. Maybe they feel that they can't fully grow or explore their potential within the village. Another reason might be to protect Konoha in their own way. They could believe that leaving and dealing with threats from the outside would keep the village safer.
One reason could be Sasuke's continued pursuit of revenge. If in the fanfiction, Sasuke is so consumed by his need for revenge that he neglects Sakura and their relationship, it might cause her to stop loving him. Another reason could be that Sakura discovers a side of Sasuke she doesn't like, like a cruel streak.
Sakura might grow tired of Sasuke's cold and distant behavior. In fanfiction, she could realize that she's been trying too hard to hold on to a relationship where she's not getting the love and attention she deserves. Maybe she meets someone else who shows her more care and respect, which makes her consider breaking up with Sasuke.
