Are 'ops' opinions? Gosh, I feel old now ...
Anyway, some things I noticed:
The first thing was your title. Is "Tommrow" supposed to be a name? Because with the letters it uses it just makes me think that it was supposed to be 'tomorrow' but was spelled horribly wrong which would likely turn me off as a reader.
Maybe somebody else could give their input on this one though because I might be the only one who would think that.
The next thing is the first 'episode' which is basically the synopsis and some comment from you. I'd advise against doing that. If you have a comment to write, you can do that in the description of the first actual episode. You don't need to give that an extra episode. Same with the synopsis. It's already displayed in the sidebar (website) or on the details page of the series (app) so there's no need to sacrifice your first episode for that either.
Now onto what I'd say is your actual first episode: I definitely agree with @kitkatxk that your paragraphs are way too long. If this was me, I'd try to have only a few sentences in one paragraph. If you're unsure how to split them up, try thinking about which sentences deal with the same subject. E.g. you have some sentences that deal with the protagonist waking up and then you have some sentences dealing with his thoughts about his foster parents. I'd put these in individual paragraphs.
You could also (if you have the app) look at how the story displays on the app and see if it's easily readable and you'd be able to come back to where you stopped after you had to take a forced break because of something. If you need to search for more than two seconds: Put more paragraphs in there.
I would also take another look at upper case/lower case and punctuation. You tend to have upper case pronouns after commas or use full stops where only a comma is needed.
Tbh I do have some trouble following what is happening storywise in the first episode too. You're jumping from the protagonist waking up to their thoughts about their foster parents to them fighting (more on that later) to their school day and then to their dinner (Btw you wrote there 'I wasn't really feeling dinner today'. Maybe I'm old and this is some slang but how does one 'feel dinner'?). Those things seem barely connected and the things that could be interesting (imo whatever happened at the school which seems to be important) are glossed over so fast that I have no idea what's really going on. Who is James and why should I care about him? Why is the protagonist in the principal's office in the first place (don't know about your country but here you'd have to have done something wrong to be ordered there and as the protagonist stated, he doesn't really get into fights)? What is actually wrong with the other children (didn't understand your description there)?
Anyway, I'm kind of lost on what is going on. If this was me, I'd probably spent some more time on fleshing out whatever is happening in school. Like, take two, maybe three chapters to really go through what is happening with the people involved, the actions and the protagonist's feelings.
In regards to the synopsis, I think it's alright to not have it in 3rd person if it fits the story. I would still agree with kitkatxk that you should work on that again. Even though it's rather clear what you mean, it's way too vague and not really gripping. Who are the 'big guys'? What actually separates them? just the martial arts? Then you won't really need the first sentence at all and could just start with the second one.
Plus I'm wondering about one thing that currently seems illogical: If only the 'big and rich' can learn martial arts, then how the heck is an orphan able to do that?
Speaking of the last point, I had said before that I'd get back to that: The protagonist learning martial arts if it's something only the 'big and rich' do already seems strange in the synopsis and would make me as a reader question how logical the rest of the story can be. I'd probably still read at least the first episode to make a better judgment but tbh I find it even more illogical after reading this one.
A possible explanation for him learning MA would have been that his foster parents are precisely part of these 'big and rich' people so he'd have the privilege to learn it. But his relationship with them is bad and he even states that he's doing it secretly. Which begs the question: How? He shouldn't be allowed to and have no way in there if there is really such a big divide between the ordinary people and the masters.
I feel that this needs more explanation (maybe not in the first episode though), otherwise, it would be one of the points turning me off the story.
Overall, I think it's a neat beginning but executed way too fast. Take some time to figure out what the focus of your first chapter is supposed to be (Strange events at the school? Him learning martial arts?), then put some more time into that one (while cleaning up paragraphs, punctuation and upper case/lower case things) while dealing with the other later and I think this might turn out well. Just doN't rush things too much or it won't be as comprehensible to your readers as it is to yourself.
