How could this happen? I never had feelings... They were stolen from me.. Never felt love... It was forbidden... I-it's hard... Why did this happen? How? How did you do that? The most impossible. The most dangerous. The most beautiful and insane... You made me love... You made a son of a devil fall for you, Jongin... You made me feel miserable in your arms... You made me feel happiness, sadness, lust, want, weakness, worrying, pain and love.. You made me live... So this will be Kaisoo devil!AU. I just had an interesting idea I hope it develops well ^^ Kyungsoo - the son of the devil Jongin - a normal your everyday teenager
