Just saw this somewhere, and tried it. While I have the gist of what's going on, I barely really only know what is actually happening since I've been skipping a lot of dialogue. In anycase, I got ending A on the first try since I just basically talked to her all the time. I tried to see what'll happen if I just keep blocking the other guy, but apparently the game forces their relationship no matter how much you prevent him talking. I found it in two ways:
1. Her relationship towards the other guy will increase as the days go by, very slowly at Normal difficulty even if there's no interaction during roam mode, this is most likely due to fixed cutscenes with her that are either triggered by day or her relationship level towards him if it increases on interaction in roaming.
2. The game will make sure you'll have less time to actually interact with the feMC the more days go by or maybe the higher your relationship with her is. During lunch initially, it would take like 20~30 mins of in-game time before the other guy would interact with her, but as I got around 100 relationship(forgot what day), the day I can also confess for Ending A, it took only 3~5 in-game mins for the other guy to interact with her even at Normal difficulty, which is near impossible to beat through esp with teachers and students automatically talking to you. That means even with only 2 maps in-between the MC and the feMC, you can get beaten fast. The only way to counteract this is to reload and hope to seed RNG she'll spawn at a much nearer place and have max time of 5 in-game mins for you to get there OR have her spawn in the General Supplies store with you. For after school, I haven't experienced it yet, but I'm sure the game will also shrink the time for you to get to her.
In anycase, NTR seems inevitable in any scenario other than Ending A. I was hoping there'd be interactions with the feMC outside Ending A as her Lust actually goes to 100. I got bored after a while, so I unlocked all the scenes.
Edit: just checked the last few endings. LMAO.
No, I'm sure it is.
Would I call this NTR? I'm not sure, seems like two guys trying to win a girl over, and the MC doesn't seem to have any past relationship with the feMC and were only mutually attracted since they were nerds, and just so happens we're controlling the MC which feels NTR. I see the NTR if they do end up together now.I don't have the attention span for this tbh, if someone can summarize this to me why it's also called a stalker sim that'd be great. The only thing I can think of is this MC became obsessed as the days go by that he doesn't confess to her and gets taken by the other guy.
