What I remember is that the mc finds himself to be able to see a game interface if he concentrates. He has time to fulfill some missions or else he will die. He can see how much money he has and he can buy special items like a key that can unlock three doors (then it's used up) and a periscope to see trough walls.

He first thinks his mission is to rape some woman but it turns out bad and he uses his ability to load the game and goes back like a day or so in time (this costs him money). It turns out to finish the mission he didn't have to rape the woman but expose her to the cops (she murdered her husband for the money).

THe second or third mission involves an older assassin girl that he is trying to seduce. He gets killed a bunch of times.(always reloads)

anyone knows this one?

Thanks. What I'm wondering about his how do you guys remember/keep track of mangas? I mean like this one, if someone asked me the same question I would know that the manga exists and that i've read it but I would not remember such a long and complicated title. Do you use excel sheets or is there some kinda method? Or is it that you guys have just a very good memory?

You can add manga into your lists so that you can keep track of which one you're currently reading. People also keep bookmarks on the browsers. For me, since I've been reading manga for so long, i just got use to keeping track of art and the corresponding stories and authors. ?
