Seeing the explanation given by someone above, it makes sense to look back. Although I didn't pay attention to these two points, it's not without my doubts. After Ben came back from the train station that day, his mother was very excited to see him, but he didn't seem to care about scarlite's arrival at all, and scarlite only got along with ben alone. Only chatting with him, when with his parents is always just sitting quietly next to ben, looking at him encouragingly... The last scene explains everything. It turned out that the creative suicide came from itself, a genius of self-salvation. When I saw the ending I couldn't help but start worrying about whether it would be paranoid because of it. On second thought, maybe he will be like Lars in "Love of Inflatable Dolls", maybe he will meet a real girl, cure his paranoia, and then make scarlite disappear. Or he'll be like John Nash in A Beautiful Mind, where the phantom can coexist with the manifest without affecting normal life.
The whole film has a deep impression on Ben's venting after being forced to do stimulants. He has always been sober, understands the feelings of his family, and understands his mother's pain. He said that when he saw his mother's tears when he was a child, he pushed all the tears back into his eyes with his hands, because he didn't want to. Seeing her sad, as he himself said, he would say it but he was reluctant to say it. It has been training itself, step by step, every step is carefully planned, for fear of making mistakes... For the first time, he said so much at once, which made people feel even more depressed. There is also the last scene, talking happily to the air, it chooses to leave, stays in its own illusory world, and can still live so well. This ending is the most perfect.
And the original soundtrack of the movie is so good, and the game music at the beginning
