Re-incarnation, but they are professionals (Non-Romance/modernday)

Judge Lee-Han with his "Trio of Justice" plus their Carry, the disguised Reporter Song. I'm dying and I love this series, thank you Author-san and to Doramaaa for the translations!

Also, let's not forget, he has a possible FL.

Bro died and woke up to his past life, he started off strong after re-incarnating using his knowledge as WWF veteran. As a fan of WWE growing up, IDK if this is a parody or just reference since the names of the wrestler are closely similar to the once I am very familiar with.

(Non-romace)

Dude reincarnated to another person's body, shocking how he looks the same as the dude he bound his soul with. This has plenty of action since he is a mercenary, quite the uptight man himself but he is balanced by the other characters for a hit of humor and entertainment. Has possible FL. (I cant choose bet. older lady or his classmate and actual GF.)

Bro just carried his friends on his back for the apocalypse! (Johan re-incarnated back to the past and learned from his knowledge and helped his friends, now family to survive.) He has a possible FL and she is badass! (Her name is Sherry BTW.)

(001_ a young merc. rescued and brought home by a lieutenant to his long lost family. He reconnects to them and becomes over protective. 10/10 for the action and the girls crushing on him.

This dude is a detective and died because of the filthy politics, returns to the past and applies his knowledge, ace it and gathered allies that burned the org. and the politician to the ground from the inside. (Bro played them like a fiddle.)

(Completed)

MC is an idol who had a tragic start of his career after stage malfunction, he failed to debut because of his face and only became a trainer. He died on a plane crash but re-incarnated to the past where he and his friends were just starting their career, saved himself and his friend from that stage mishap and used his past knowledge to rise to the top winning the idol contest. (they won!)

(Non-romance but I love their friendship!)

Bro is my hero! (He met the best doctor in the worst scenario, the doctor died after a tragic fall and the knowledge of that doctor was passed to him as well as the ring. Dr. Tae-Soo became a military Dr. to a war zone and bro managed to make things peaceful in the boarder. Those two generals actually respect him and salutes whenever he saves their soldier. Bro even went to the north to help the poor people and save them from illness.) He needs a raise.

The adventure and plot so

Even businessmen???

Dude's a chef.
