My Childhood Friend and I Returned to the Past, and He Broke Down

After an accident, Liu Yunhai's life rewinds, sending him back to infancy.

Then he discovers that his childhood sweetheart has returned too!

Just as Liu Yunhai is getting ready to team up with her and create the perfect ending,

he suddenly realizes that something seems off about this world.

A childhood-sweetheart regression romance, a straightforward heroine, a certain country's parents, a System, and some surprise bonus content.

This is not a parallel-world rebirth. It's the same world and the same timeline. In other words, the world has fallen apart.
