I think it depends on the context and development of the story. Sometimes the actions and expressions might suggest love, but other times it could be more ambiguous.
It depends on how the novel portrays the relationship. Sometimes, one character might love more intensely than the other at first, but over time, the love can become equal. For example, in some romances, there are misunderstandings that initially make it seem like the love isn't as mutual, but as the plot unfolds, they realize their true feelings for each other.
I'm not sure which specific 'girl do you love me story' you're referring to. There could be many stories with such a title or theme. It might be about a boy asking a girl if she loves him and the various emotions and events that follow, like her response leading to either a happy relationship or a heartbreak.
Perhaps 'love me do' novel is a romantic story. It might center around a couple where one has to constantly prove their love to the other. The plot could involve misunderstandings, reconciliations, and ultimately, a deepening of their love for each other as they overcome obstacles together.
