This isn't angsty!! Just a little bittersweet, so don't let the blurb fool you.
A story about a cute octopus monster looking for its mother. (Its mother gave it its name, and it has a human form.)
She hatched me, then abandoned me.
In the fiftieth year after she sealed me in the deep sea, I broke free and went out, only to find an empty room and a gravestone at the door.
Mom... Mom, why did you leave me behind? Why did you leave all by yourself?
According to the rumors, the enraged monster overturned the seabed, devastating all living things. Then the Heavenly Dao captured it, made it sign a contract, and cast it into different worlds. Its fate was unknown.
World One: Tentacle Monster and Sensitive, Affection-Starved Mom [Interstellar]
From the moment she was born, Chi Zhiyi knew that the sky above her was gray. People died around her every day, the smell of rotting flesh drew in the vultures, the elderly murmured weakly, and children wept as they died.
Here, living was simply a matter of not dying.
A low-grade planet couldn't give rise to advanced life, until one day she found a little tentacle monster. The creature, a little bigger than her palm, lay in a soft heap and called her "Mom."
World Two: Tentacle Monster and Mom in a Rental Room [Modern]
After personally sending her alcoholic, abusive father to prison, sixteen-year-old Chi Zhiyi moved into a dreary rental room, holding the hand of her six-year-old sister, who had an intellectual disability.
She hated her sister because their mother, the only person in the world who had ever loved her, died giving birth to her. But she also loved her sister for her face, so much like their mother's, and because they were each other's only support in the world.
Until her intellectually disabled little sister used her tentacles to caress her skin, inch by inch.
"Mom, if I lay eggs, you won't be afraid of me being a monster anymore, right...?"
World Three: Tentacle Monster and Post-Apocalyptic Researcher
"Mom, you can study me." The little tentacle monster lay limp in her palm, offering up its hearts for her to extract and study as if it were the most natural thing in the world, even though it felt pain many times more intensely than a human.
Later, she swallowed all the monster's tentacles and murmured softly.
"If I give birth to a little monster, I can study another monster without having to watch you die, right?"
World Four: Tentacle Monster and Mom
-Why did you abandon me?
-Because you're a monster.
There will probably only be these four worlds. I won't add more.
A cute tentacle monster who has its mom at the center of everything, and a mom who loses her memory in all sorts of places.
[Why did you put Mom back together, only for her to kill me?]
[Mom smells so good. When she kills me, can I die in her arms?]
