Road of the Wedding: Yuusha no Konkatsu

A real-life marriage fantasy, here we come!

Damien and his friends have defeated the Demon King and become the heroes of time.
In a world where peace has come, there's no way they can just marry a princess and live a slow and comfortable life...is there? Life from now on is not as sweet as in "fantasy!"
After saving the world, the brave Damien and his friends are faced with a series of powerful enemies in the name of "reality," such as marriage, money, and job-hunting...?

If it's going to be like this, it might have been better not to defeat the Demon King!
