In the Interstellar era where the strong are king, soft and cute species are almost all extinct.

Tu Mianmian, who crossed over, was given a ruthless Duke husband, a husband who could destroy Mechas in minutes.

As a lop-eared rabbit who had just refined his human shape, he felt weak, pitiful and helpless.

So, he resolutely ran into the entertainment circle, relying on his sky-defying appearance to garner large amounts of fans from interstellar society, including his own gong/husband.

It was night, and the Duke who was going to improve the relationship between husband and wife walked to the door and saw a fluffy lop-eared rabbit lying on the sofa…

When Tu Mianmian found himself sleeping beside his gong with his rabbit body stretched out, he scared himself. Sitting up in shock and dazed, he unconsciously stomped the Duke’s mouth. Shivering, he retracted his rabbit paw, but was caught by his gong with a cold face.

Tu Mianmian: …I, I, I am willing to cut off this rabbit’s paw!

Before he could finish speaking, the iron-blooded Lord Duke approached his mouth at the speed of light: Chuu~~ ( ˘ ³ ˘)♥

- Description from Novelupdates

Fate is weird. Of all the people in the world, why would it select me to send to a different world?

And what is it trying to do? Put up a show by giving me a system? But oh well, what do I care.

The previous owner of this body was a cripple and looked down on, but now I can slap their faces with my system.

Young masters? Get out of my way!

Princes? Geniuses? Oh please. I have a system. That does not mean anything to me.

I know that I am not the greatest. But fate gave me a cheat system, and I am not wasting it.

I am going to do whatever it takes to conquer this world. Fate forced me to do this. It isn’t my fault if I cause some ruin on the way.

Everyone felt pity for poor Marietta’s situation, however, the truth was that Marietta found the General very dreamy… The story of a 30-year old General with a scary face (who was actually quite nice), and the tiny and adorable 18-year old Princess in their times of conflict and of lovey-doveyness.
