So by accident, I've found this story plenty of times. But for one reason or another I don't seem to fave it or put an alert for it since it's not done(to my knowledge that is.)
Anywho, I can remember a lot about it so this might be an easy find.
Sess and Kags meet because she was a customer service worker in Sess's company. They date and what not, but on Father's day Sess decides to break it off because Sango told him that Kags was pregnant and her brother was the father. A couple years later Sess goes to see Inu-papa where he learns the existence of his son because Inu-papa wants to take Sess's custody of his child.
That's basically what happens in the beginning, the rest is a bit fuzzy.
Can anyone help? Thanks in advance!
