Both the dramas have the same CP and the leads have amazing and sizzling chemistry together. If you like Zee and Nunew and/or #NueaLian, this series is a must have on your watchlist

By strange fate the leads get close to the other lead who looks exactly like their loved one. In prince William the ML is her brother's look alike where as in My Lethal Man it is the girl who is the one with similar looks with another girl

Both are historical dramas situated with fantasy;
Both have moon/sun archetype;
Amnesia female lead with unhinged male lead;

The main characters in both dramas have to act as their doppelganger from super rich-rich family with evil family members. Pretending to be the other person, they also have to take over some big business company. The overall mood and atmosphere of the shows are quite different, though.

Similarities:

- BUTS & TT are both university and sports themed
- Each has a rich ML
- One of the ML's are trying to find out who they are
- Starts our with FWB (Friends with Benefits)

Differences:

- BUTS is swimming themed while TT is soccer themed

je to podobne tomuto serialy rozhodne stoji za schlednuti oboje bylo uzasne a velice me bavily proto se na oba dva rozhodne podivejte....

i don't know if this is helpful but there's an amnesia subplot in both that was dragged out endlessly and then everything wrapped up in a rush

Part 2 in particular is similar because it takes place after one of the characters died and was resurrected and is still misunderstood by the world as being a ruthless but powerful killer who practices sorcery (Wei Wuxian and Naksu). Their partners (Lan Zhan and Jang Uk) are now powered up characters who fear no-one and are able to protect their loved one, regardless of their past or what the world thinks

Both have immortal male lead characters who suffer from their fate until the female lead frees them. One thing I found similar was that both male lead characters had guilt and pain and constantly had to bury people throughout the time they were alive

Both dramas involved 'siblings' with ill-fated relationship, murder, investigation and revenge. Additionally, both our ML have the same character name. Sungjoon with memory loss and Sunghoon who hold the key of the memory.
