You know when you have this story in your head that you know you don't have the time/ability to tell completely, so you just tell your friends and internet strangers about it? This is like that. This felt like a series that the author had a lot of plans for, and instead of creating a complete series, they summarized the main points and released it like that.
And like whenever I tell my friends about my OCs and vice versa, I am now pretty invested in this. I want to know more about them. I want to read an entire hundred chapter series about this. I want more action, more awkward romance, maybe some slow burn, definitely more cool grandma
