I'm not entirely sure specifically what 'suki suki visual novel' is about as there could be many different visual novels with this name. It might be a story about love and relationships, as'suki' means 'like' or 'love' in Japanese. Maybe it involves the experiences and emotions of the characters in a fictional world.
I'm not entirely sure as I haven't played it specifically. But generally, a visual novel often has a story with different characters and plotlines. It might be about relationships, adventures or personal growth of the characters within the story world.
