A 'blow love story' could potentially be a story about a love that is disrupted or 'blown' away, perhaps by unexpected events or misunderstandings. It might also refer to a love story that is as light and fleeting as a gentle blow of wind.
Consider a 'blow love story' where a girl has been in love with a guy for years. They are about to get married when suddenly, the guy meets his long - lost sister who reveals that their family has a genetic disease. The guy, fearing to pass it on to future children, breaks off the engagement. This unexpected 'blow' completely changes the direction of their love story.
I'm not sure. It depends on the specific context of what 'Blow' refers to. If it's a movie or a book, you'd need to look into its background and the author's or filmmaker's statements.
It's hard to say for sure. 'Blow' could be a complete work of fiction or have some roots in reality that have been significantly transformed in the storytelling process.
The 'blow hot blow cold' story often refers to someone who is inconsistent in their attitude or behavior. For example, a person might be very enthusiastic about a project one day and then completely cold towards it the next. It's like the fable where a man blows on his hands to warm them and then blows on his soup to cool it, showing his changeable nature.
