Congrats on finishing your first project. It's one of the hardest steps, and you made the leap! I'm gonna try to be more detailed for this one. Hopefully, my thoughts can be helpful.
You set up the vibe well with the title and the opening, which is great, but that also instantly sets some expectations for the reader. The writing aims for realism / a more grounded vibe, which is great for a sentimental piece, but I feel like it's not fully commited.
The spoken dialogues work well, doing the heavy-lifting even. The lines are fun to read and capture the characters' personalities. However, sometimes it's not the case for the narration.
For example, the line "We begin watching the movie. This is an action movie, fortunately, all four of us have a passionate love for this genre. Even Manny and Ryan are shutting up to focus on the movie." does not sound like a sentence someone would say, even to themself, mainly because it falls flat when it's supposed to indicate a semblance of passion. The line could do with a small touch-up like "Heck, yeah, this is an action movie. Fortunately, all four of us have a passionate love for this genre. Manny and Ryan usually could not stop talking over the film, but now they keep their focus on the screen."
Obviously, everybody writes differently. However, as someone who likes to write in a grounded tone, I would suggest first deciding on what emotion you want to evoke for each scene. Everyday-things are mostly mundane. Without a specific and strong angle, they will fall flat.
Last issue I found is lenghty lines. Longer sentences don't necessarily mean it's better. Considering the nature of the medium, generally it's better to pack the writing into one-or-two-breathable sentences per click. Readers need to breathe. Helps with the pacing, too, and makes it look neat / not crowded. If you really want to show a longer line on one screen, you can use pause {w} more often.
Overall, it's a good starting point. Well done!
