The characters may be depicted as complex beings where their emotions are a double - edged sword. On one hand, their emotions give them depth and humanity, but on the other hand, because in this fanfic emotions are 'foolish', they are also a source of their downfall. Maybe a character's love for another is intensified by the presence of Sakura, but this same love, being a foolish emotion, leads to a series of problems and misunderstandings in their relationships.
They could be shown as either trying to suppress their emotions because they know they are 'foolish' or constantly struggling with them. For instance, a character might see the beauty of Sakura and feel a rush of emotion but then quickly try to push it away because they think it's unwise to feel that way. The fanfic may use the Sakura setting as a trigger for these emotional responses and then show how the characters deal with them.
Perhaps in this fanfic, the idea is that emotions are 'foolish' because they cloud judgment. For example, if a character in the Sakura fanfic is in love, that emotion of love might cause them to overlook obvious problems or danger, thus being 'foolish'. It could be a central theme explored in the fanfic about how emotions can both enrich and also endanger the characters.
There's also often a sense of desperation. Because the pursuit is relentless, when faced with obstacles, the characters may become desperate. They might take risks or make sacrifices that they wouldn't normally do. For instance, in some novels, a character might sacrifice their social status or family ties just to be with the one they love.

He might be constantly pushing himself a little too hard in his rehabilitation, which the medical staff or the members would have to caution him about.
Often, Hermione is portrayed as conflicted. On one hand, she's dealing with the unexpected pregnancy, which is a huge life change. And on the other, it's with Draco, someone she used to despise. So she might be feeling a mix of confusion, fear, and a strange new - found affection. Draco, on the other hand, could be shown as initially shocked and then slowly accepting his role as a future father. He might be feeling a sense of responsibility he never had before.
The characters could be portrayed in relation to their beliefs about the serpent and the rainbow. For example, if in the true story there were people who feared snakes and saw rainbows as a sign of hope, the characters might reflect those feelings. They could be on a journey of discovery related to these symbols, with their personalities shaped by the cultural or superstitious connotations of the serpent and the rainbow.
It likely portrays their emotions as a mix of confusion, sadness, and anger. The children being taken away would be very confused and sad.

And Pa, he has to deal with the pressure of protecting his family. The children also have to grow up quickly and face adult problems like helping with farming and dealing with dangerous situations, which all contribute to the tragic portrayal.
