Hey there! I'm so sorry for the late reply!
1) the main point of leaving the story there was to allow the readers to imagine how Jongin moved on after Seolin left. I don't really like telling everything and instead I like to leave endings that trigger readers to think > < So yeah, I don't think there will be a POV for Jongin, sorry!! ;-;
2) Honestly, I've had many thoughts and ideas for a sequel, but I'm still not really sure whether there will be one. Maybe I will add a sequel when I'm less busy?? But I'm glad I was able to move you with my story LOL, thanks for liking my fanfic!
3) Uhh I actually don't remember what inspired me... I just suddenly developed so many feels for Kai so one day I wanted to create a cliche romance fanfic about him where I can put my imaginations to use. They were supposed to end up with each other and be all happy in the end, but my ideas for the story kept changing as well as my life which resulted in such a depressing ending :/ Good luck on your story though!! Wishing you the best :)
Thank YOU for staying with my story till the end, and I really appreciate you for taking the time to send in your questions! I hope I answered all your questions, and if you have more, don't hesitate to ask me!
