Well, 'overflow visual novel' could be a specific kind of visual novel. Visual novels are known for their combination of storytelling and visuals. In this case, 'overflow' might imply that it has something in excess. It could be an excess of emotions in the story, too many plot twists, or an overabundance of beautiful art. It aims to immerse the reader in a unique narrative experience.
I'm not sure specifically as there could be many novels with this title or concept. It might be about a story where the so - called 'love' is false and there is an overflow of this false love situation, perhaps in relationships that are full of pretense among the characters.
One horror story could be about a Lifereef overflow system that suddenly had a major leak. All the water started pouring out, flooding the area around the aquarium. It damaged the flooring and electrical equipment nearby. Another might be where the overflow mechanism got clogged with debris. This led to the water not flowing properly, and the water level in the main tank rose dangerously high, almost causing the fish to jump out.
Not having read the 'overflow with fake love novel', it's impossible to accurately name the main characters. However, in a novel with such a theme, we might expect characters who are either victims or perpetrators of the false love. There could be a naïve character who falls for the false love easily, and a manipulative character who spreads this false love for their own purposes. Maybe there's also a character who discovers the truth about the false love and tries to expose it or break free from it.
It could be that the market demand for their visual novels declined, so they decided to stop. Or perhaps there were internal problems within the company that led to this decision.
One great read could be 'Snow Crash' by Neal Stephenson. It has elements that are often discussed in Stack Overflow - like virtual reality and complex technological systems. It's a classic that combines cyberpunk elements with a really engaging story.
Since 'overflow visual novel' is not a well - known category specifically, it's a bit difficult to recommend. However, if you like visual novels in general, 'Danganronpa' series might be of interest. It has a lot of plot twists, complex characters, and an 'overflow' of mystery elements. Another one could be 'Fate/stay night' which has a vast story with different routes and an abundance of character development.
