The Lotus Casebook (2023)

Yue Jin Zhao and Yue Qi lived together in Wuyan Village for three years. With an amazing "resonant" relationship, they knew nothing about each other's origins. They worked together to venture outside, wishing to get the old memories back. They were involved in mysterious events such as the rebellion of the Qihun Holy Sect and the Blood Sacrifice of Luojiabao, and in the process of fighting against the Holy Sect, Yue Qi suddenly regained her sealed memories and emotions...

While i will not say both dramas are same, co it's not. Each have it's unique blend of same little elements though.
The demon, immortal and human trio set to solve cases. Their interactions. From enemies to best friends. The case solving journey brings them closer understand their past stories.

Both are funny shows, avoids gratuitous romance, and have solid plot and action.

I Am Nobody might be the funniest cdrama this year, and if it keeps up the quality, will be one of the top shows of the year. 9+ rating show. I liked MLC, but I'm loving IAN.

A main character hiding a secret regarding his health/life with last wish/goal to find remains/body of beloved family member before it is too late. Excellent bromance. Mystery. Humor. Mains solve series of puzzles/cases that all connect and lead up to end mystery/confrontation. Cornucopia of interesting characters throughout.

Both revolve around a skilled swordsman/woman known to be the best and have their own fighting style.

Both leads want to let go of their past, keep their identity a secret and live a normal life but end up getting involved in the drama to protect the ones around them.

MLC is a bit more light-hearted, comedic and revolves around solving mysteries while RoA has more action, swordplay and martial arts - but both have similar premises

Brilliant male leads using their wits to maneuver hardships in wulin world. Strong support characters.
