depressing graphic novels

Read the complete synopsis before reading the novel. ---- An ordinary guy was thinking of confessing his love to a girl at the end of summer break, but he died before he could confess. He reincarnates into a new world and realizes he is in the world of the game he played. The game was a bit complex, with lots of choices and twists, but in simple words, it had a protagonist and five heroines. Making the correct choices would keep all heroines alive and end up with the protagonist, while incorrect choices would lead to the death of the heroine. The person responsible for killing the heroine if the player makes the incorrect choice is Akechi Ryuki, the best friend of the protagonist. Now, our normal guy possesses Akechi Ryuki. What is he going to do? Will he do the same as the real Akechi Ryuki would do? Or will he do something even worse? Or will he ignore them? ---- MC is a good person, but he has many perverted fetishes and fantasies, which he will make heroines fulfill since heroines also have such fetishes. Also, not all women in the novel are for the MC. The MC already had his harem, while other characters also have theirs. If you are reading the novel, don't complain about MC's not making moves or stealing others' harems. MC has his harem, and he doesn't want it anymore. ---- Read the tags below before reading the novel. Later, don't complain about why I did that.
