In some stories, when Anpanman fails to save a village or a group of people from a disaster. He always tries his best to protect everyone, so when he can't, it's a sad situation. He might feel like he has let his friends and those in need down, which is a very heart - breaking feeling for him.
One possible theme could be friendship. Just like how Anpanman has his group of friends in his own world, it could be paralleled with the strong bond among BTS members. For example, a fanfic might show the BTS members having adventures similar to Anpanman's, where their friendship helps them get through difficulties.
Some fanfic writers like to take the cute and friendly nature of Anpanman and blend it with the charm and popularity of BTS. One way to find such fanfic is to join BTS - focused fanfic reading groups. They usually have a collection of various fanfics, and with the Anpanman - BTS combination being rather unique, it might be a topic that some writers in the group have explored. You can then ask for recommendations specifically for Anpanman BTS fanfic within the group.
