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.
