Sirius Black- So cold

So... yeah, I know this video it's maybe not the best of all, and that is really confusing. So I will clear some points.
1. I put a scheme where Sirius starts having trouble with his parents when he is sorted in Gryffindor, before that, he was ''loved''.
2.But Sirius as a child was punished for everything he did "wrong", so at his first night in Hogwarts, he has nightmares of his past.
3.So yeah, he is locked in his room all summer when he goes home.
4. But in Hogwarts he is really happy, because of his best friend James and all the pranks and jokes they make together. In the video, the two are in the forbidden forest with fireworks and all that stuff.
5.Then you can see the last time Sirius return to the 9 3/4 platform.
6.Sirius has a talk with James about how the fights in home increased. And you can see the last fight of Sirius and his father.
7.How after the fight, he went with James.
8.And I know that in the real story, Sirius does not like Walburga, but here, Walburga was the one that saved him, so the last part are memories of the two, when he was younger, when they loved each other. And he goes to her grave, because even if they did not like the decisions of the other, she was who saved him and he will always remember that.
But of course if you want to interpret the video in other way, go ahead.
There's only one line, so if you speak spanish there are subtitles for that line. Yaaaaai.
The song is 'So cold' by Ben Cocks.
