• Both are based on Ding Mo's works.
• Although in LMIYD, Simon's character seems to be more intense than our captain in WASFIL, both are haunted by a past which motivates them to be best at what they do.
• We see many cases being solved in both, ultimately leading to the one main case.

• The female leads in both are well established personalities in their respective industries.
• The male leads are introduced as interns at the FMCs workplaces.
• Age gap couple - Older Woman × Younger Man
• Man chases woman first. MCs in both series give the 'golden retriever' - extremely devoted to their love interests.

• ML in IIMH can see the past, while the lead in IHYV can read other people's thoughts.
• MLs have had a life-altering encounter with the FMCs in the past.
• The FMCs are strong, independent women who are great at what they do.
• The couples in both series work together to overcome their adversities.

• The main lead of RLP (Pian) is extremely similar to the main lead in Tawipob. Makes me wonder if they were actually inspired by Tawipob, what with the number of times it's mentioned throughout RLP.

• The MCs temporarily get a chance to come to the modern world - soak in all the changes in the world in an innocent child-like awe. Both of them hold huge respect for their country & its well-being.

• Both have Older Woman/Younger man tag.
• FLs in both treat the ML as a little brother.
• Strong female leads.

Forensics is a shared focus in both dramas. While "Trace" solely focuses on crime solving episode - to - episode, "I Know Your Secret" has a little bit of drama and added intrigue.

The male leads in both are quite similar, except for their jobs. Both have experienced a trauma in their pasts which have brought them to where they are now.

Both have the possibility of romance which isn't explored but hinted at.
