its a movie aired in 2020... Its hard to say, the DVD may not even be out yet, so its impossible to see unless its a recording from the movie theaters using a cellphone or video camera. THe usual waiting time between the cinema movies and DVD to being available to download on the internet is usually from one to a few years. So i wouldnt be surprised if you had to wait a few years to view the HD version for free
I do know a website that has it for free, but it's a pirate site so there are a lot of pop ups which lead to viruses. I just recommend you watch it on a laptop/pc so you can close any tabs that open. I'm not sure if I can post the link to this or not.
i recommend that you install a virtual machine, install ubunto on it and only then enter dubious websites, even if you get a virus, it wont infect your pc, you can just delete the virtual machine and problem solved
That was weirdly nothing I expected it to be like quite creepy and unexpected but it has the cliche Korean anime art style
