There's 'You Deserve Each Other' which is a really fun grumpy - sunshine romance novel. The couple starts off in a rather strange situation where they seem to be at odds, but as the story unfolds, they realize their true feelings. 'The Unhoneymooners' is another great one. The main characters are complete opposites, one being more grumpy and the other more sunshine - like, and their journey to love during a case of mistaken identity is really engaging.
In grumpy sunshine romance novels, the grumpy character often has some past experiences that made them closed - off, like a bad relationship or family issues. The sunshine character, on the other hand, might have had a more positive upbringing. As the story progresses, the sunshine character's optimism starts to break down the grumpy character's walls. For example, in 'The Hating Game', the female lead's cheerfulness gradually makes the male lead less grumpy.
Another option is to check out Tumblr. There are a lot of Twilight fans on there who might be into this type of pairing. You can search for relevant tags like '#sunshine x grumpy twilight fanfiction' or something similar. There could be posts about it, reviews, or links to the actual fanfictions.
The contrast between the 'sunshine' and 'grumpy' characters. In Twilight, the series already has a diverse range of personalities. This pairing allows for a new dynamic that can be really interesting to explore. For example, the 'sunshine' character can bring out a different side of the 'grumpy' one.
The 'redemption' trope can also be present. The grumpy vampire may have a dark past or some guilt associated with his vampiric existence. Through the love of the other character, he may find a path to redemption. For instance, he might start to control his more violent vampire instincts better and become a more 'human' - like in his emotions and actions, all because of the love he has for his neighbor - turned - lover.
There's also 'Twilight' to some extent. Edward, the vampire, could be seen as a sort of grumpy neighbor figure in Bella's world. The story is all about their forbidden love and the challenges they face due to his vampiric nature.
