Yeah, I don't know how to mention so... yeah... anyway... I don't think they have something like a suicidal pill cause if you look at his face closely as he is crying and this says otherwise, not to mention after the guy died, there's a would on his left arm and that wouldn't be possible cause Maria didn't use a sharp weapon as you saw and also if a suicidal pill would do that.
Also, guessing that's the villain at the end there, and for some reason, I wanna smack his face.
Thanks for the translation!
