Honestly, the timeline is still a mystery. Especially after Nojiko's rework. It is not yet clear whether Nojiko immediately took the children to her or not. However, the first flashback in chronology shows us how Nami returns from the camp (the religious camp mentioned in Wiab?) with a new friend. Nika acted like a normal guy for his age. After Summer said that she liked MC, Nami made her first move - she tried to embarrass Nika. Then a series of small flashbacks show how the three of them became friends. However, Nami made her second move - she tried to copy Summer. The turning point was Amber's second flashback, when Summer kissed Nika. From that moment, their friendship with Nami began to crumble. In Nami's eyes, she became the third wheel. It is not entirely clear whether this really happened or Nami began to try to pull the blanket over herself, that even the incredibly kind Summer began to find her annoying. Next is the most mysterious flashback. Meeting Elsa. From here we learn that Aunt Summer strongly controls Elsa’s figure, considers Nik a bad influence for Summer. It’s not entirely clear, this because of the financial situation of Nika's family or possible grievances related to Summer's parents or perhaps even Nik's parents. However, it is still a big mystery where Summer lived, who her parents were. The last flashback - Summer has to leave for a couple of weeks, and she he is very afraid of something. This is where the clear things end, and the rest is left to guess.
After Summer disappeared, Nika changed a lot, became more wild. He also got closer to Nami again, switched his attention to her, began to manipulate and fight. From here I have 2 theories. 1-Nika began to take revenge on Nami for what she did. 2-Nika, consciously or subconsciously, also had feelings for Nami.
Nami's solo path, the scene by the lake shows the audience a scene of not only Nick smoking, but also Nami smoking, obviously not for the first time. Considering how Ocean likes to attach importance to such things, they were both rowdy. Towards the end of high school, there was a terrible incident. Nika was hospitalized. After that, they made a certain agreement. The details are not clear, but there are a few clues. They clearly agreed to remain silent about certain things. Nika forgave Nami. However, everything had its price. Both of them changed again. Especially Nik, of whom only a shadow remained.
There are still a couple of questions left. Who is this blonde with whom Nika ran away in the rain? The only thing I remember is SG, the very first version, meeting Victoria in the rain. After the rework, this scene changed.
Second question: If Nika and Nami didn't have any relationship in the past, does Nika understand that Nami always had feelings and not just now?
Third question: Did Summer realize that Nami had feelings?
The fourth and most important question: Were they really not in a relationship? Nojiko’s reaction is too strong for just a joke in the style of *I’ll make you eat tits*.
