This is based in the BTS manga We On; Be The Shield. I just added the ship Namjin and mpreg into it. So its the same story, just with that twist and the lead female is the reader.

If you don't like Yaoi or mpreg, then don't read ahead.

I do not own the original story or the characters, I just own the idea of making the female lead be the reader, and adding mpreg and Namjin in it. 

I do recommend reading the original story on manga rock. 

other then that enjoy!
