So the app was named after Jooin's birthday... Honestly, I know that moren than 50% of people are happy with Jooin ending up with Yahwi, but Cain was the best choice for me. I'll say it again, the whole past life story was not necessary for the main story. This is the worst story EVER. Is totally garbage!!!
So, are hey actual brothers or.......?
They are and it's not incest... I guess it's just obsessive behavior plus some psycho shit.
I guess something happened in the army which turned the older bro like this
His friends said he was the same as always at one point in response to him beening over protective i have a theory that it happened maybe when theyre dad died or even before that.
