Similar script of finding the murderer amongst themselves. Some people who played in WITM had also starred in GOS. They both vote out the murderer by finding evidence of crime and motive and pinpointing who is the likeliest to have murdered the victim. Every episode has a new and intriguing storyline .

Same script of people finding out who the murderer is among themselves by using clues and figuring out the motives and the process for the murder

They both have a similar vibe and have a lot of horror concepts. The players in both shows go around trying to uncover the mysteries surrounding them.

Very similar concept overall except The Truth S2 has a bit more elaborate backdrops/buildings than Who's the Murderer. The Truth S2 also has more jump scares.
Who's the Murderer has been running for 9 seasons now while The Truth is pretty new.
They're similar to each other in the fact that one of 5-7 members is a murderer and there is a detective(s) that is trying to suss them out. All players have to go around finding evidence and discovering the motives of the suspects and they vote at the end to find who the Murderer is.

Both are college dramas and very light-hearted. The male leads are both standoffish and smart but they are the ones that fall in love first. Both dramas' couple chemistry is cute and off the charts. There isn't much family drama either. Both similar to drama love 020
