The Little Amnesiac and the Old Ancestor in an ABO World

I transmigrated into this world and dropped from the sky onto the old ancestor, who had just awakened after a thousand years. Unfortunately, I lost my memory.

But it was fine. I had a System, and the old ancestor had brains.

According to the System, I was an unloved Beta in the family. My fiancée despised me for being a Beta and had fallen for my Alpha half-brother. Families of equal standing mocked me, saying I couldn't even protect my own Omega and was a cripple who needed to borrow a "benefactor's" prestige to throw my weight around.

What a joke.

I could accept all that, but my unserious face-slapping System couldn't.

In less than an hour, the System had been exposed.

As it happens, I am the current, and youngest-ever, head of the imperial Lin family.

[An unloved Beta?]

System: [Who would dare dote on the family head?]

[Mocked by families of equal standing?]

System: [They're all enemies. Of course they'll laugh.]
