- Description from novelupdates

Lin Wan transmigrated into a book and became the stepmother of the male lead. Her husband was an undisputed big shot in commerce and was cold, decisive, and ruthless. Her stepsons were each more eccentric and difficult than the other… until they took part in a variety show as a family. Five families were competing, each of which was perfectly harmonious…

Except for Lin Wan’s family. Naturally, they were the control group once the variety show aired. Every other family would have scenes of the parents cooking and the children helping adorably, a picturesque sight of family harmony. On the other hand, Lin Wan and her three stepsons ignored each other as they had crackers and ham for their dinners amidst an eerie silence. At night, while the other families went out happily stargazing and moon-watching, Lin Wan and her stepsons told each other horror stories, leaving the viewers petrified! Netizens were flaming as they watched, but they soon noticed that the control group was changing…

Even though the eldest son insisted that he disliked his stepmother, he sneaked off to buy her a scarf! The second son declared his favorite person was his father but voted for his stepmother instead! The third son was also caught putting his stepmother’s favorite candy below her pillow! The netizens were shocked, but it’s true: the tsundere stepsons were extraordinarily close with their stepmother!

I found out that my dad, who is actually my adoptive father, is also a crossdresser by accident. The fact really shocked me and tortured my spirit, so I chose a forum on the Internet to pour it out.

The most terrible thing is I gradually realized that I had fallen in love with my dad…

What should I do??!! Does he love me? Should I just keep hiding my feelings?

The Strongest Magic meets the Mightiest Mecha.

I have stolen Golden Mechas from the deepest vaults of the most tightly guarded fortresses in the world.

I have personally destroyed more armies than the top three superpowers have in the span of the Absolute War - combined.

I burned down the terrorist megacity of Habon.

I was expelled from the Union of Heroes at a younger age than people are allowed in.

I have talked to Ancient Gods, loved women, and devoured mechas that would make superpowers cringe in fear.

I have faced demons head on in moonless nights others fear to speak of during the day.

I am deified in a thousand cultures, and labelled as the devil incarnate in the rest.

I am the Mecha Emperor.

You may have heard of me.

Excerpt from Chapter 1

This is where it all began.

A junkyard.

Oh no, this isn't your clean, mechas-only junkyard that was the 'starting point' of many mecha geniuses out there.

I have seen and heard my share of rags-to-riches stories, and many of them claimed that they had started from 'junkyards' and slowly grew to be where they were right now.

From Zero to Hero, they declared.

You can do it too, they said.

As long as you work hard, everything is possible, they claimed.

I call bullshit.

Life doesn't work like that.
