Welp, the crazy part wasn't wrong, I mean it's also mentioned/proved multiple times in game, the LI was def the type of more extreme, picky yandere (amplified on that 'yan' part that the dere blurred into kireru/yangire) which instilled the tension of stepping on landmines you have to proceed with caution for having a forced talk with the dangerous kind of mentally unsound person.
So if anyone's looking for a sweeter yan(dere) you could check out another game by the same developer 'My Valentine'!! Or play that one after this, that's what I did to refresh lol.
This Alex guy said he didn't bite, he WOULD do much worse, won't give you any heads-up (or painkillers, help I would've died or passed out honestly) for your harmful punishment, and even the kidnapping will be the least concern of yours. Personally, he wasn't the type of yandere I prefer, but I did enjoy this dark-horror terrible mood the situation set up plus that 1st end about ring finger plastered the bloody icing on the cake. Despite the true/happy end, I found it more satisfying on the third end where you can play along and left unscathed, it was the best win-win you could get out of it all, but you know.
