SPaG: there are a couple moments where you misspell Johnny as Jhonny, and there are a couple instances of open quotation marks— where you forget to indicate that the dialogue has either ended or began. I recommend putting it into google docs or word, it'll highlight where those bits are. Also, as a rule of thumb, you should start a new paragraph with each new bit of dialogue.
Story itself: as for the plot itself, it feels a bit like it's lacking a hook. I'd like to know Aryan's thoughts on Dadachi, on Nathan's refusal to elaborate what exactly the job is, and why Aryan agreed to bring Jonathan if Jonathan seemed reluctant to go, because the opening establishes that Jonathan's been left home alone before. In short, I feel like you could go a bit more in depth on Aryan's opinions on the things and people around him. Other than that, I think this story has good bones and I'm excited to see where it goes :]
