They all died (apart from V) I cried a river T_T
Jimin drowned himself in the bathtub
RapMon dropped the cigarette at the gas station so the fuel and gas will burn up and kill him.
Suga burned himself in his hotel room.
J-hope gave himself a overdose.
Kookie was hit by a car.
V killed the guy so he will probably be put in jail for the murder.
Jin.... there is a legend in Korea that if you sleep with lilies you will die because they suck out all the oxygen from your body (he was seen with lily petals and a lily was formed over his heart)
