My name is Seo Nanai, and I have two childhood friends.
When we were ten, Rika died in a car accident, then turned into a monster and stayed by Yuta's side.
- You mustn't fall for anyone else!
- You mustn't leave!
- You mustn't have any other friends!!!
“Yuta, Nanai, we'll be together forever and ever and ever.”
Monster Rika was extremely possessive. She went berserk and bound the three of us together.
If we didn't do what she said, she'd attack us.
Yuta and I had no choice but to stay away from everyone else, like two little beasts in exile, huddling together in loneliness.
But humans are social creatures. No matter how much I forced myself, I still needed intimacy to satisfy my emotional needs.
So, as the lonely longing went on day after day, Yuta and I were the only ones who could comfort each other without restraint.
But I didn't like living this way. Every time we cuddled, I would be overcome by an endless weariness.
When could I escape from the two of them? When could this twisted relationship finally end?
Then Rika attacked someone again, and a man who called himself the strongest found us and brought us to study at Jujutsu High.
At last, I began to try.
# Starts when they're ten, relying on each other to survive
# Some dark, obsessive vibes
# Not a multi-love-interest story. The male lead is confirmed and the only one
