I think this is the first manga I read that shows 'polyamory'
some might not know it but polyamory is where you have more than 1 partner (which isn't considered as cheating)

What's the difference with polygamy?

Polygamy is a mostly religious thing where a man marries multiple women and the man is in charge. Polyamory is a Relationship consisting of multiple people in which everyone is equal.
I wonder how much will this emotionally wreck me
From the comments I've read it looks like it's pretty angsty
time to start reading it
If u finish it, it actually has a good ending. Both alive n shit too lol!
