I saw this one nice "simulation system" that has a complete loop; you gain one sim per 30 days, in a random world, and you can use a free mode which is text based and a paid-by-power-level mode that is isekai based that unlike free mode you can do quests. At the end of sim, you gain 10 random rewards, which you can pay to buy, afterwards gain 1 random free of the unbought in 10
fuck off with this self-NTRing shit, lmao even the protagonist repeatedly said he wasn't into her anymore and didn't want to compete with MC for her, this fucking loser
