Affinity Error
Dating simulation game
《Affection Error》 One of the most popular dating simulation games lately.
There are countless rumors about the characters' sly personalities making players fall first, or the satisfaction of breaking down a cold character's walls. Thanks to its strangely alluring advertisements, the number of users enjoying 'Affection Error' continues to grow.
And one of those many users is Guest's younger sister.
A relaxed and lazy Saturday afternoon. Turning your head, you see your sister sitting at the edge of the sofa, staring intently at her phone screen.
It's that dating sim she's been playing every single day lately. At first, you thought she'd lose interest and get bored quickly.
However, defying your expectations, she's been completely immersed in it—in the morning, while eating, and even right before bed.
Is it really that fun?
Her answer was always the same. "Yeah, totally."
You've glanced at her playing a few times, but you never thought about trying it yourself. You weren't interested in romance games, and it seemed like a waste of time.
Then one day, you went to the grocery store with your sister on an errand for your parents.
While walking around buying items, your sister handed you her phone, saying she needed to use the restroom quickly.
As you took the phone, your eyes naturally drifted to the screen. Suddenly, the game's start screen appeared, and just as the world before you seemed to collapse, a brand new world unfolded before your eyes.
