I was recently scrolling through the Rankings on Webnovel and came across Ero Meter. My first thought was it seems to be similar to the Parameter Remote Controller novel and Love Parameter Manhwa. Then I started reading it.

Ero Novel Review

Summary
The Ero Meter tells the story of Jack, an average schoolboy who is in secretly love with his childhood friend but his childhood friend likes another boy. This disappoints Jack and as he thinks about moving on, he gets Ero Meter.
Ero Meter is just like its name showing s*x desire floating above the girls’ head as well as the show provides dialogue options during the conversation which helps Jack to modify the girl’s desire.

Review
Now the review, this novel is not much but a pure wish-fulfillment adult novel filled with s*x. The writing is average. The “actions” writing could be written in more detail. I will praise the author in the context of character consistency. The characters’ behavior has remained most of the time consistent except for the main character.
Another thing I didn’t like was how easy the author made it for the main character. When he got the Ero Meter, the main character got everything: money, girls & s*x
There’s not much build-up. The author should focus on build-up more than the “action” itself.

The dynamics behind the Ero Meter could also be polished more. New functions could be introduced.
Struggles and Build Ups would have further made the story better.
But while saying this, I admit that I am asking too much because it is nothing but a wish-fulfillment story.
In short, don’t expect much just enjoy the story.

Novels To Read If You Like Ero Meter Novel
Stealing Spree

The web novel, Stealing Spree, stands out due to its effective treatment of a harem storyline featuring over 20 distinct female characters. The tale’s focal character, Onoda Ruki, starts as a somewhat despicable individual who ‘steals’ girls away from their boyfriends, yet he undergoes significant personal development as the narrative unfolds.
The author succeeds in creating a diverse array of female characters, all with their unique character traits and arcs, which contribute to the novel’s authenticity. While the story suffers from slow pacing and the inherent challenges of managing an extensive harem, it keeps readers hooked with cleverly used tropes, engaging romantic interludes, and captivating character progression.

Supreme Harem God System

The web novel Supreme Harem God System offers a mature and engaging narrative that tracks the exploits of Nux Leander, who is translocated to a cultivation realm. Armed with a unique system that bolsters his cultivation through encounters with women, Nux’s journey to becoming the world’s most potent Emperor is an exciting ride.
Although the cultivation aspect and the system could be fleshed out more, the novel holds the reader’s interest through a harmonious mix of humor, action, and a captivating plot. The gradual maturation of Nux, along with an exceptionally well-crafted harem, adds an extra layer of intrigue, making the novel a delightful read.
