Who has seen the murder of Kindaichi Hajime Computer Villa? Can you tell me the general idea?

Do you want a detailed spoiler? I watch animation.

Jin Tianyi and Michelle got lost and ran to a snowstorm villa, where seven reasoning enthusiasts happened to gather. The screen names of these seven people are Agatha, Patricia, Germany, Zheng, and Watson. They only met through the internet before, and they didn't know each other's names and looks. Among them, Agatha and Luan Bu have an online love affair. Jin Tianyi was trapped by the heavy snow all night, and the tramping and Spencer were delayed. In the evening, everyone went back to their rooms to have a rest before arriving at random.

After Jin Tianyi checked in, he received a phone call saying that the monk had been killed. When he got there, he found that the monk was dying, and Watson and Luan Bu arrived one after another. After investigation, everyone has an alibi. They said that they were with Agatha when they arrived and got a call from Patricia. Later, when Jin Tianyi asked, Patricia denied calling. He was killed indiscriminately and identified Patricia before he died, but Patricia had an alibi. Everyone always thought Spencer was a man, but Spencer's body was found to be a woman.

After Patricia was poisoned, Jin Tianyi searched her computer and found that seven people had conspired to create a murder that was considered an accident. Jin Tianyi identified Agatha as the murderer. Because Spencer has a crush on Random Steps, he and Agatha agreed to pretend to be themselves when Random Steps came. Because the others were not there, because the random walk came late, they thought Spencer was Agatha. When they were together, Agatha killed someone and ran away, and then called a random walk to the crime scene. I didn't know the truth and made an alibi for Agatha. I mistakenly thought that there were only two women out of seven people, and took the woman who called him and killed him as Patricia. Taking Spencer's scarf at random and comparing it with Spencer's relic wool ball became the evidence that Agatha stole the column.

The murderer is actually the fiancee of the person killed by the Gang of Four. She killed the real Agatha and attended the party in Agatha's name.
