符致逸-Love you more than anyone

Recently ,i found out that a lot of couple in the drama tends to fall in love easily .
Some of them just met each other for 2 or 3 days ,they already fall in love .

Is tat possible for it to be happened in reality????
If the girl and boy bcum fren for long times ,is tat impossible for them to bcum couple later on???
If a guy like the girl ,he ll proposes to tat girl .... he din propose means  he just assumes her as his fren ???

The only thing i know for now is ,if a guy really like u ,no matter hw ,he ll stay bside u ,u no need 2 chase him behind....
