it’s not, look at the date 3 ending guide and it’ll show you how to get the nsfw tenebris scene right there. you need i believe 10 tenebris points and 3 yandere points to get the other option
If you wish to continue the game into Date 4, avoid investigating the noise entirely. If you want Tenebris' bad ending, you need to follow the Date 3 bad end guide.
No actually there's a way to get a killer mc who doesn't care that temebris kills people it's very specific dialogue options but it'll allow mc to ignore the sight of them killing the person obviously it's still a bad end but you get an extra scene with tenebris a sex one.
