Recommendations for NOT to watch C-Dramas

• One and Only (it's the most heartbreaking drama I've ever watched but it is painfully gorgeous. ML is tortured to death, FL commits suicide, and most of the supporting characters get bad endings, too.)
• The Red Sleeve (true story and the ending follows history)
• Good Bye, My Princess (FL commits suicide, ML grows old and wanders the desert looking for her.)
• The Hymn of Death (true story, follows history, both leads commit suicide.)
• Moon Lovers: Scarlet Heart Ryeo (FL dies in the past, returns to the future, ML remains in the past, leaving them separated by time.)
• Don’t Forget My Love (ML and FL die together in the end.)
• Revenge of Royal Princess (both leads die together.)
• The Immortal Promise (ML dies, FL doesn't find out until a year later and dies of grief/sickness when she learns.)
• Cheng Xi's Song (both leads live, but don't end up together due to the ML's actions and FL's desire for freedom.)
• Heart Medicine (ML sacrifices himself for the FL.)

and these dramas end well for the leads but I'd still consider tragedies:

• Buried City to Shut All Lights (the drama has an open ending but the movie sequel has a happy ending for the leads. However it's an incredibly sad drama with a lot of deaths including the ML's only friend, multiple supporting characters, and the leads' unborn child, and both of the leads are emotionally damaged and broken by what they've gone through. 
• Battle of Changsha (the leads and their son survive and are together, but literally every other character dies including FL's entire family, and both leads have trauma.)

And I just realized I didn't notice the cdrama part and tossed a few kdramas in there, oops! ?

I haven't seen The Wolf, so I don't know, sorry! The only drama I know for sure has a sad ending that I've never watched is For Married Doctress (FL dies).
