Everyone has a different thing but in my opinion it's disgusting. I was really happy when I found out one of my favorite BL manga got more parts to it and especially when it was focused on their kids. And I could excuse an age gap, but all the love interests all took a part in raising them. It's fucking disgusting.
It was really cute! <3
(SPOILER)
I just loved the fact that they fell in love each other (all of them) when they were children (age gap)!
And is it only me or are there no females or are it just male-females there?
