Break seems to have a soft spot for Sharon compared to how he treats most other people. This was greatly shown when Sharon got kidnapped by Vincent and Break willingly gave up Cheshire's bell, which he treasured, in exchange for Sharon.Break was shown in early chapters to tease Sharon after she'd met with boys her age - he insisted Gilbert was 'her type' and aggravated her again after she met Oz. He tries to keep her away from dangerous situations, as well as keeping "dark" information away from her. For example, Break told Reim that he didn't want Sharon knowing about Sablier, saying that he didnt want her to know about something so dark. However, since the second coming of age ceremony, he realizes that Sharon isn't a little girl anymore and can take care of herself.
Sharon desperately wants to be of use to Break and help him in battles. However, Break usually goes on missions without telling her, as a result of him not wanting her to worry and also wanting her to be safe.
Sharon thinks of Alice as a little sister. Although Alice seemed reluctant to let Sharon treat her this way, she seems to be fine with it now. She often gives Alice advice on romance. Alice and Sharon both care about each other, as shown when Sharon got depressed about how Break didn't tell her about Sablier, Alice tried to cheer her up by biting her cheeks. Overall, the two seem to be good friends.
When she revealed her harisen he was intimidated by her. She and him, however, do respect each other and are friends. Oz and Sharon's relationship does not ever seem to go beyond "friends", though, and interestingly enough, they don't talk very much in the series. When they do talk, it is usually briefly.
On multiple occasions, Oz has shown concern for Sharon, as seen when he went to check on her after she was poisoned, and when Rufus Barma unleashed Dodo on her, while defending Break.
Although they have few interactions in the manga, he and Sharon have been shown to be quite close friends, and seem to have an understanding of one another. They have great respect for each other, and have never argued, despite the fact that they both have frequent altercations with the other characters - Sharon often gets angry with Break, while Gil is constantly bickering with Alice. In the same way he teased her about Oz, Break has suggested that Gilbert is her "type", because when they first met he was "cute" and "suited her taste for young boys". Surprisingly, given the difference in their personalities, the pair get along exceedingly well, and because of this Gilbert remains one of the few people who has not been attacked by Sharon's infamous paper fans.Sharon is somewhat caring towards Gil, often showing genuine concern for him, and providing comfort or advice when he needs it. When he returned from the capital with Vincent after battling , she dried the rainwater from his hair with a towel, and encouraged him to tell Oz that Vincent was his brother, as she knew that he was burdened with keeping it a secret. After the events of the second coming of age ceremony, Sharon invited him to have tea with her, so they could talk privately. She knew that he hadn't been sleeping well since 's death, and that he was suffering just like the others, even if he didn't show it. She advised him that crying when he should would prevent him from breaking later on, showing that she is deeply concerned for him, and doesn't want to see him suffer.
