both shows have unconventional methods of getting what they think is justice, DAS seems more drama and law oriented. Whereas LM deals with the law and has action as well as drama.

they both deal with not your typical lawyer. Both lawyers want justice . They have unusual law offices, Threy work hard for justice.

They both have lawyers fighting for justice and the lawyers are determined to see justice served. I like in lawless lawyer that there is action and adventure and the lawyer and his team aren't afraid to get their hands dirty. . In both the lawyers make sure the law is used for them to have the guilty pay for their crimes. In DAS they are not dealing with crimes but divorcee cases.

they both deal with an alternate reality. In switch on it's a virtual reality. in Sweet dreams its a dream world. They both have the leads trying to get back to reality.

they both deal with either a virtual reality or an alternative reality. The leads have to fight to stay alive and solve the mystery so they can return to the real world.

The both have a virtual reality. The leads have to figure out who the bad guy is and work to get back to the real world without getting killed in the virtual one.

the main leads are both bodyguards. There is a fun romance. Now the difference is in bodyguard SAO it;s the female lead who is the bodyguard. Where in the Charming Stepmom its the male lead. I liked both of them, Hint: don't analyze for credibility just enjoy it.

they are both about the living interacting with ghosts. in Ghost host Ghost house you have two living men interacting with a whole family of ghosts. In Let's Fight Ghost you have a human exorcist working with a ghost girl.

They both deal with the mystic and mystery. Now Triage is about the ML lead desperately trying to save the other ML by reliving the same events over and over again trying for a different outcome. Now Sao Song Winyan is about two young adults trying to help a ghost solve her murder. So it is different but similar in the fact there is a mystery to be solved. I liked both I hope you will try it.

they are both about ghosts If you like one I think you will like the other. Both series have humor and a mystery surrounding the ghost(s).

They both involve time travel. They both have a mystery to solve. They both have a romance to the story.

They both involve time travel and both leads live in the same apartment just at different points in time and they meet in the apartment once a day for a specified amount of time. I thought "Love in time " was good. "609 bedtime story" i haven't finished and I just hope for a happy ending.
