@AwakenAtlantis Hello, love~! The short answer is yes, but here is the long answer (I apologize for the wall of text.)
While the ending is coming close, I have no plans of making a sequel to Limerence (as of now), but I do plan on releasing 'bonus chapters,' much like the ones you've read throughout the story. These stories will take place after Limerence and will give you an insight into their life. Some SFW, some not, will touch upon things people are itching to know (wedding/grandchildren/old age).
I'm not sure if you've checked out my Tumblr, but I released a longish Fem.ReaderxGeneral Iroh II drabble, which takes place in the original Limerence/ATLA timeline. Yue and Zuko make an appearance as his grandparents (not going to lie, I got emotional writing that, ha~!). It has received a ton of love, and as a result, I plan to turn that short drabble into a potential short story (maybe 5-10 chapters).
There is also a spin-off series in the works as well, once Limerence is done. Multiple ships have arisen on my Tumblr page, and two of the top ships are YuexAang (Yuang) and YuexAangxZuko (Yuengko). So, I have a whole short story in the works for Yuengko.
Another idea that has been toyed with and suggested is Limerence but in Zuko's POV only, and it's something I am interested in doing, but I haven't confirmed.
The ending of Limerence also sets up the character development for a particular individual (who shall remain unnamed), and I've been toying with the idea of making a spin-off series of their story. But it is something I will decide once the series is done and if people want it.
In regards to any LOK stories, it is something that interests me. Mainly General Iroh II and Mako because they have no canon partners at the moment, and I love keeping my stories as canon-compliant as possible.
I went off, I'm sorry! But I hope that answers any questions you had, and feel free to ask me anything! I love interacting, take care~!
