I strong think that it's the same person BUT it'd crazily cool if they were twins!!!

Imagine if there really are two jongins'/kais'
Maybe jongin was always jealous of kai for hving sehun back then and so- yeah im not gonna get ahead of myself XD Looking forward to your next chapter~~~

k I don't know.. I vote for same person but now that I think about it hmm.. if he has a twin, then that's a ing twist..where does the other twin go? Did he died? Or does he'll be making a comeback

I doubt they are two diff people

I'll wait until the next chappie

I wont comment -_-

The comments section in this is so infuriating like wtf u people are messing up my mind rn ;.;

I really truly think that kai and jongin are like two different people but how can they share the same experience which can only one person has? and sehun really is a dumb because how could you didn't even realize that ur boyfie are two different people or have a different personality disorder? are you lowkey twotiming them? HAHAHAHHA i love you and keep going!!

Because I like it cliche ^_^

I dont like throwing speculations around--i rather go with story flow and be surprised later :) my future reading enjoyment is on your hand awesome author! :) i look forward for the upcoming chapters

I felt like i'll ruin the story for everyone..oh well since everybody's saying it...i feel like Kai and Jongin are twins. If im not mistaken Kai had changed clothes when he came to see Sehun, slightly drunk and disarrayed taking in puzzles...tht was probably Jongin..since he kind of confessed his love to Sehun before they made love. And also when he was stuck in the elevator he told he couldnt resist Sehun..maybe he was forced to restrain himself cuz his presence was unknown and Kai had already won Sehun's affection. But the issue with Kai disappearing..i have no clue..but my insincts tell me that its Jongin's child tht Sehun gave birth to..of coutse tho..i'll read to find out :D ♥♥

Reading these comments below opens up a whole new world to me..woww so many theories! But knowing your style, my jaw will still drop again :)

Diff person ...twins nd Kai left coz jongin had with sehun..nd jongin was his silent lover or something...lol my imagination

U Know maybe Jongin was Force to take over for his twin's future by his parents orders cuz his older twin died or is in coma... u know in high society its the older heir that carries the burden of the company and employees. So now he has to pretend to be someone he is not. So maybe the night Sehun saw him last with different clothes was Jongin himself saying Goodbye to Sehun by addmiting he loved him... and goodbye to Jongin and welcoming his new identity as Kim Kai.

hmmm..i was inclined to think it was A, but after rereading the previous chapters it seems possible that jongin is kai's twin, who was always locked up in the house, forced to live up to parental expectations? he could've fallen for sehun from a distance? which makes me wonder who sowon's biological father is if that is the case...is my imagination too fertile?
