I haven't read this story, but I've reviewed the synopsis. The premise seems familiar: the protagonist, Mc, is betrayed by his friend, family, and girlfriend, which is quite common. In his second life, after dying, why does he choose to become a villain after experiencing betrayal? Take Naruto's Madara for instance; he was betrayed by Black Zetsu, much like many other villains in various stories.Instead of this predictable plot, why not portray Mc in his second life as someone who finds it hard to trust others, who is cautious and even prepared to resort to extreme measures like a suicide bomb if betrayed again? I dislike this synopsis because the protagonist seems naive; how could he not realize something was wrong with his lover, friend, or the people he cares about days or weeks before the betrayal? It's frustrating to see a character portrayed as careless and clueless.It would be more compelling to mention in the synopsis that Mc doesn't die alone but manages to take down one or two people with him before his demise. Hope author accept my critique, if you want to make another novel please.
