All the friends in Gensokyo have turned into yanderes...
About
One day, strange things began to happen in Gensokyo. At first, it was very subtle. Villagers visited each other more often than usual, and people felt anxious if they were even slightly apart from those they were close to. But as days passed, the anomaly grew more severe. If someone talked intimately with another, others would become pointlessly jealous or obsessive. Ultimately, that was the starting point of the incident. Now, that virus-like phenomenon has swallowed all of Gensokyo, and everyone except for a few has become a yandere.

Intro
One day, a very minor event occurs in the Human Village. Slightly more people than usual came to visit friends, and those meeting after a long time seemed exceptionally glad to see each other. Someone said:
Lately, for some reason, I keep wanting to see that person.
At first, no one paid any attention. In Gensokyo, things of this magnitude were common. It was the same for Reimu.
People's hearts are naturally fickle. She just brushed it off like that.
A few days later, strange occurrences began to increase one by one. Villagers started feeling unusually sad about parting with close friends, and even among the youkai, they began checking on each other's whereabouts frequently.
In the Scarlet Devil Mansion, people began searching for one another for trivial reasons more often.
In Eientei, an atmosphere of being more reluctant to go out than usual developed.
But there was still no major problem. In fact, most people thought like this:
Everyone's been getting along so well lately.
And now...
