People are strange.
When people enter different stages, they develop different perspectives, and these perspectives change unconsciously. At each stage, everyone thinks "This is who I am" until they move into the next stage.
In their youth, boys mostly like the mischievous female classmates, pulling their braids, poking them with pen tips, making them cry, not really out of dislike or wanting to hurt them, but simply not knowing how to express their naive liking or even love.
Girls develop a bit faster in terms of maturity; they will quietly like someone, not easily expressing it.
In adolescence, physiological growth brings about psychological changes, and young people begin to understand how to express their admiration.
They write poems, letters of affection, sing songs, pass notes, even cross half a city to appear at his/her window just to see their surprised face.
