This Japanese Monogatari Isn't Lame - Chapter 8 - . Someone is Here (Please Collect!)

What was originally an ordinary day, suddenly became a historical turning point. Enormous, mysterious Cubes appeared all over the world without warning and as if Judgement Day’s spears, inserted themselves into the blue planet.

From inside the enormous Cubes, endless streams of monsters gushed out alike raging tides, utterly defeating the unguarded armies of each state in the blink of an eye.

In order for humanity to preserve its final embers, the heads of states issued orders of retreat, to no longer attack the Cubes but rather to cling to remote cities, which they turned into self-sufficient survivor bases and around which they built 100-meter-tall Walls of Life!

Many years later, while bearing the heavy weight of history, the first expeditionary force brought back a world changing piece of information. The Cubes possessed exceedingly high intelligence and they regularly transmitted mission instructions to humans nearby. The mission rewards were incredible.

Since then, humans rushed out of the confines of the walls and once more set foot on the wasteland!

Xu Anran did not know that her husband Qin Xiaokun was a wolf in sheep's clothing until she died.

He deceived her feelings with affectionate illusions, conspired to seize her family property, harmed her family, and in the end, he ran her over in his car in order to be with his true love justifiably.

After she opened her eyes again, Xu Anran returned to the day she married Qin Xiaokun five years ago.

Those scumbags better not think about touching the things that belonged to her in this lifetime!

What she suffered in her previous life would be avenged one by one.

She walked up to Qin Xiaokun's rival Jiang Rongyan in front of everyone and asked him with a smile, “Mr. Jiang, would you like to marry me?”

Behind him were the unpleasant expressions of the Qin family.

He thanked her for the invitation. This would be the cuckolding version of the face-slap script specially customized for Qin Xiaokun.

-Xu Anran wanted to stay away from relationships in this life, but she did not expect that after the agreed marriage expired, the man refused to let her go now!

Jiang Rongyan, “You want to flee after you finished using me? Heh, you're dreaming.”
