MAA

The main character's family dies in a road accident while coming to visit him. The main character uses an app that uses the personal information of dead people to create a "virtual avatar" of that person. The main character installs the fictional character of his dead mother and talks to her on video call. With personal information, the fictional character of the main character's mother realizes the son's blood sugar and energy level are low. And since Mother died first, her ID came first, but the others came late.
