Love is Harsh but Yields Great Treasures

I'm not good at summaries but There is a lot of love, hurt, pain, and comfort. Sirius's soul mate is Luke and Harry is soul mates with Severus and Lucius. There's mpreg. Harry is pregnant Luke was but lost the baby and talks about it but later on he'll get pregnant with Sirius and not Percy. Percy is the traitor and Luke is good. Voldemort aligned with Kronos (Chronos) and Percy.
