One popular wgm oc fanfiction could be those that focus on creating unique love stories between the original characters and the inserted 'oc' (original character).

First, you need to have a clear idea of your original character (oc). Decide on their personality, background, and what makes them unique. For example, if your oc is a shy artist, think about how that will play out in the wgm setting. Then, familiarize yourself with the wgm concept and the usual scenarios that happen in the show.
His charm. Taecyeon has a very appealing personality, and in fanfics set in the 'WGM' world, that charm is magnified. Fans love to read about his romantic side.
Romance is a very common theme. Fans love to write about the OC falling in love with Lee Min Ho, with all the sweet moments like first dates, confessions, and kisses.
His bandmates would likely be involved. They might be the ones who first notice Jungkook's headache. For instance, Jin could be the mother - hen figure, trying to get Jungkook to rest and making him some herbal tea to soothe the pain. J - Hope could be the positive energy, trying to cheer him up and make him forget about the headache through his jokes and antics.
There's also a fanfiction titled 'Love Beyond the Screen'. In this, the OC is a normal girl who accidentally gets involved with Lee Min Ho in a series of events that are both humorous and romantic. The writer does a great job of building their relationship gradually, making it very engaging to read.
One thing that might make it different is the theme of 'the taste of love'. It could be that the author approaches the concept of love in a more unique way compared to other fanfics. For example, it might focus on a more mature or complex understanding of love rather than just the typical puppy - love scenarios.
