Notes:

I'm not gonna link a sauce directly just so i can warn people twice about checking it, it's so f----- up, it's about a boyfriend and girlfriend where boyfriend goes to the suicide forest to kill himself and girlfriend follows him and then goes full yandere and ends up hanging him while r----- him and then hangs herself with him. (And then their bodies were probably discovered by logan paul) but if you absolutely must know, the name is "Dokuritsu Fuki (Daienjou Ikare Ikasare Iki Ikare)"
