One great Suga x Jin fanfic is 'The Bond Beyond the Stage'. It beautifully depicts their friendship evolving into something deeper in an alternate universe. The author does an amazing job of capturing their personalities. Another is 'Shared Moments'. It focuses on how they support each other during tough times, showing their bond through various heartwarming scenarios.
You can try Archive of Our Own (AO3). It has a large collection of BTS fanfics, including many great ones about Jin. The site is well - organized, and you can easily search for Jin - related fanfics by using the search bar.
I really like the fanfic 'Jin's Shining Journey'. It focuses on Jin's journey in the entertainment industry but with a fictional twist. It shows his struggles and how he overcomes them, all while maintaining his charm and kindness. It's really inspiring for fans.
It could be his dog. Dogs are often considered man's best friend, and in a story about a boy, a dog would be a very likely candidate. The dog could be loyal, always by the boy's side, and they could go on all sorts of adventures together.
It's also possible that the girl's best friend is an older person, like an aunt or a grandmother. They could have a special bond where the older person gives the girl advice and shares stories from her own life, and in return, the girl brings youth and energy into the older person's life.
Li Qin and Zhao Liying had the best relationship. The two of them had worked together many times, including in 'Dream of the Red Chamber' and 'Run! Brothers " and variety shows. They worked together frequently and had a lot of time and opportunities to interact. As a result, they had a deeper understanding of each other and became good friends. In addition, the interaction and tacit understanding between the two were also appreciated by the audience. The other search results didn't mention Li Qin's best relationship with anyone else.
