"What will the future look like 600 years from now? What would it be like to risk everything and fall in love with someone from the future 600 years from now?"
The "I" who is worthless in real life tries his best to escape from the shackles of life. While saving others, he is saved by someone at the same time.
(You must watch it to the end, it's very exciting...)
Intention: Stay true to yourself, always be brave, and live up to your heart
