This story didn't work for me I'm afraid.
There's a lack of conflict in the beginning of the story. Everything goes smoothly, there are no obstacles, just exposition. The actual conflict just starts practically at the midpoint.
MC's parents are very bland. I liked to see that they were Korean, but that doesn't affect the story. The story tells about United Korea, but it also doesn't add to the plot. I didn't see the point.
In fact, both families are stereotypical: the Asian parents are harsh and intelligent, whereas the hispanics are poor and have a lot of kids that don't have enough to eat.
I had a hard time sympathizing with the characters. I just didn't get invested. Everything feels so... emotionless. I couldn't grasp any feelings among the writing. There's a part when MC just bursts, "I hate both of you. Why are you trying to ruin my life?". It felt so off that made me cringe.
It's just so weird that they are sixteen. They behave and talk like little kids. I thought they were eight, or ten, tops, until MC's mother said their age. I'm still wondering why they are so childish.
The reason why the mother didn't want Dylan to date a Jewish girl is a mystery to me.
I liked the ending though. I like how simple it is. It is great in its simplicity. But a story isn't made just by its ending.
