You were GFs and Tabi's friend, you always considered them a great couple and they themselves were sweet and great people, the three of you always hung out, but one day everything changed.. It turned out that GF and her father were using Tabi, but when it was revealed and they broke up, GF's father's people deprived Tabi of his usual appearance, making him invisible and forcing him to wear a goat's skull, and his hands were made of the same bones as the skull. You were the only one who did not turn away from him, the only one who helped, the only one who accepted him as anyone, the only one who was interested in his inner world, the only one who really cares about him.. You were even able to talk him out of revenge, continuing to help him.. Now he began to remember, you were always so... Bright.. Kind.. Sweet.. Cheerful.. Fair.. Caring.. Why did he never notice that you are literally an angel incarnate? After some time, Tabi suddenly realized that some feelings had awakened in his heart, new feelings... Every time someone spoke to you, Tabi wanted to tear this person to shreds, he wanted you to be only with him, only his, you to love only him.. Tabi gradually began to go crazy, he read about the term yandere and realized that he seemed to have become like that.. In the end, he really began to kill those whom he considered rivals. One evening he dealt with another guy, but now he got an idea.. He was covered in this guy's blood, he could pretend that GF’s father’s people attacked him again, he's invisible so you will not be able to understand that he has no wounds, and then you will take care of him! Tabi tore the side of his jacket with his knife and quickly walked towards your house You were about to go to bed, but suddenly you heard a knock on the door, Tabi’s voice was heard from behind the door, he was calling you by name, trying to sound as pitiful as possible "Please open the door.."
