I'm sorry, I haven't read the 'kisi se kya bichar gaye novel' so I can't really say what it's about. Maybe it's about the relationship between characters or some kind of event that makes people wonder what others think.
I'm not sure specifically which 'main khayal hoon kisi aur ka' you are referring to. It could be a song, a poem, or something else. Without more context, it's difficult to tell the full story.
Sorry, as I don't know the exact nature of 'kisi se kya bichar gaye novel', I can't recommend similar ones precisely. But if it's about relationships, you could try 'Pride and Prejudice' which is full of characters speculating about each other.
Well, 'tu pyar hai kisi aur ka' implies that it's a love that is for someone else. In a school love story context, it could be about a person who has feelings for someone else in the school. Maybe it's a story of unrequited love, where the protagonist loves a classmate who doesn't feel the same way. It could also be a story full of jealousy and longing as the person watches their beloved be with others.
If it is a song, without listening to it or having more details about its lyrics and the context in which it was created, it's hard to give the full story. But generally, a song with such a title might be about unrequited love or a sense of self - effacement where the singer feels like they are just a thought in someone else's mind, maybe longing for that person to notice them.
The main plot could be that of a heartbroken student. They discover that the person they like is in love with someone else. So they have to deal with the pain of seeing their crush with another person every day at school. They might struggle to move on and find themselves constantly comparing themselves to the other person their crush loves.
It seems that 'bichray gay ab kaise novel' is a very mysterious and perhaps not - well - formed description related to a novel. If we assume 'bichray' is a character or a theme, 'gay' might be a quality associated with it like being cheerful. 'Ab kaise' could be something like 'how now'. However, this is all just speculation. To really understand, we would need more information such as the origin of this phrase, the language it comes from originally, and any related cultural or literary context.
I have no direct knowledge of this 'yes ka no ka hanbun ka light novel'. But generally, light novels are known for their engaging stories and unique concepts. It might be centered around a complex relationship where the characters are constantly faced with choices that can be simply yes or no, or perhaps a more nuanced 'half' option. It could also be a story that plays with the idea of uncertainty and decision - making, using these concepts as a driving force for the plot.
