(The pairing in this story is 285.)
One day, a strange dating sim suddenly appeared on Hanjo Tachibana's phone.
There was only one romanceable character. He had an unusual hair color and unusual eyes, and lived in the world of the game.
Wanting to figure out how it had suddenly appeared on her phone, Hanjo Tachibana decided to give the game a try.
Although it was hard to raise the character's affection, and there was no option to pay for a speedrun, Hanjo Tachibana still thought it was a pretty good game.
But one day, the game suddenly disappeared. Just like the day it had appeared on her screen, she opened her phone the next morning and it was gone.
No matter how hard Hanjo Tachibana searched, she couldn't find a single clue about the game.
Just as she was gradually giving up, she met a man in real life.
He was exactly the same as the one in the game.
