A Record of a Mortal's journey to Immortality:

The animation in the video is about a mortal who leaves everything behind to become an immortal. He encounters a trial where he is trapped in a world of illusions and there, he sees his family and his sister who is now all grown up. He misses them, and all he needs to do is wear the red bracelet to forever be trapped in a dream filled with love and bliss. To be with his family again who he has not seen for hundreds of years, he yearns for that deep down. Although they have all passed away in reality, he gets to live with them in the illusory world, should he choose.
