After Losing My Memory, My Yandere Little Brother Wallpapered Me

After a car accident leaves me with amnesia, an alpha stays by my bedside and tells me he's my boyfriend.

I keep quiet.

He's not my type.

Because he looks like trouble.

With nowhere else to go, I can only go home with him.

The alpha's apartment is strange. There's a clean, empty basement that looks unoccupied, nutrient supplements filling the fridge, and brand-new chains.

The alpha gently explains, "We used to have a dog. It wasn't very obedient."

I look into his beautiful eyes, and for some inexplicable reason, I feel a chill inside.

He loves me so much he grovels at my feet. He's practically a me-first absolutist.

And I'm just an alpha with injured glands and barely any pheromones. How could I possibly have found such a young, gorgeous boyfriend?

Until one day, someone nearby smells the possessive, top-tier alpha pheromones clinging to me and asks timidly, "Lu Yunchu, why are you with the crazy guy who forcibly marked you?"

My fragmented memories fall into place.

I remember everything.

That chain, that basement, the nutrient supplements in the fridge: they were always meant for me.

The so-called "boyfriend" is the younger brother I raised with my own hands and then abandoned, the one who hates me to the core.

I have to escape.
