Review Detail of Leiden_Dez in Villainous Me: Help! The heroines are yanderes!

The novel should be called "the counter-attack of the weakest and most resentful hero in the world" in just 20 chapters we learned about him, a puppet of the system, a despised bastard, the weakest creature in the world, thrown out of his family for a false accusation, abandoned by his fiancée and betrayed by his only friend. I really don't understand why the author wrote such a disgusting main character, and also tries to pass it off as a "villain". Even if it gets better further, the beginning generally discourages the desire to continue reading.
