As I promised here is the companion story of "Falling" that will solely tell the story from Kyungsoo's POV.
The first thing you need to know about this story is it won't be continuous. I might skip scenes and it's not something that should be read as a standalone. So for you guys who haven't read "Falling" yet, you might want to start there first. I might reference things that I already explained in "Falling" and didn't want to—or too lazy to  explain again. Anyway, you can read it here.
I know "Falling" is a bit girly and light (or am I the only one thinking that way?). However, "Captivated" won't be. I'm telling the story from Kyungsoo's POV and honestly, with the personality of his character, there's nothing light about him. I will try my best to inject some Taeyeon-humor in him, but that might also be rare.
And since I'm a girl, I might struggle a lot to channel a boy's way of thinking. The language will drastically change. God forbid Kyungsoo will say "Eeew" and "OMG." So please expect the narration for this story to be blunt, straightforward and occasionally offensive.
I will try my best to bring all the KyungTae feels. Enjoy!
