I just finished reading and as of now, I'm enjoying the story.
Read the story now
There are some improving points though and things to pay attention to.
Tenses: you change tense from one paragraph to another throughout the chapters and it becomes hard to follow the story this way. Decide which tense you prefer more and stick to it.
There are some formatting bugs too, once or twice dialogues or descriptions are split in the middle of the sentence and continue in another paragraph. It isn't bad but, just a heads up :)
I noticed and felt that sometimes the behaviour and thoughts of the MCs didn't really match their age realistically. There were times where their train of thoughts was somehow too mature or childish, but there wasn't a character development that could have supported that yet.
This is perhaps a personal preference but I suggest adding the dates, like the year the scene is taking place at the beginning of the chapter. One can better follow the time jumps between chapters and be aware of the timeline that way.
Nonetheless, I like where the story is going for now, as well as the alternating POV divided by chapters. That way, it's easier to follow the narrative instead of having a change (or more) of POV in one single chapter.
Keep up the good work!
