Well, 'Rumbling Hearts Visual Novel' stands out for its music and sound effects too. The background music sets the perfect atmosphere for each scene. The sound effects, like the gentle rain when a sad scene is on or the bustling noise in a crowded place, add to the realism and immersion of the game.
In fanfiction, a purr rumbling in her throat might signify contentment. It could be that the character is in a pleasant situation, perhaps around someone she likes or in a place she feels safe. For example, if it's a cat - like character, it's a natural expression of their well - being.
The author could describe it in relation to the character's body language. For example, 'As she leaned closer, a purr rumbling in her throat, her eyes half - lidded in a look of pure relaxation.' This combines the physical manifestation of the purr with the character's overall state. Also, comparing the purr to something else can be effective. 'The purr in her throat was like a soft thunder in the distance, a gentle but powerful vibration.'
In the 'Attack on Titan' series, there is no clearly defined canon romantic interest for Levi. His character is mainly focused on his role as a soldier and his fight against the Titans. However, many fans like to ship him with various characters in fan - made love stories.
