I love seeing the emotional development characters go through when they have their ups and downs of a relationship. Romance is a typical and messy thing in real life, and it just makes everything feel relatable too. It can also show themes of what makes a relationship a red flag and really reveal how toxic couples can be sometimes. If it was horror, the feelings that would be most shown is anger, fear, sadness, and confusion. The characters wouldn't be that focused on relationships and development-more on surviving. It depends on the book though.
