Lovely Runner (2024)

Both dramas are about one of the leads suddenly dying and the other attempting through time travel to save their life.

Both FLs time travel into the past to save the ML who has died in the present. It's then revealed that the ML was secretly in love with her a long time before she believes they first met.

In both series, he saves the life of one of the characters by time travel.
They have crime, romance and humor.
The character has to go back in time several times.
It takes place in modern times.
A handsome man and a cheerful, lovely girl.

Both dramas in which the characters go back to their past to change their life in this case, Go Back Couple is set solely in their College Days.

In both the dramas FL time travels to past in her high school time.
Both FL has a crush on the male lead .
It's really funny and lovely drama I highly recommend it

in both dramas, the female leads have an injury and are at a low point in their lives when they meet the male lead :)

The ML will fall into a coma, and the FL who wrote the story of the ML who is a character in his book, will enter the space time of his Novel to be able to save him and change his destiny

-time travel
-sorta time loop (ML dies no matter how much the other partner tries to save them)
-butterfly effect (future changes becoz of past actions i.e. there is only one timeline)
-chemistry is good
-romcom

Difference is that Triage a medical drama and shows a more prominent time loop and ML is able to write what happens in each while FL in LR cannot write or say anything about the future to past people.

painful past, kind of time travel but not time travel
A story of love and friendship between five high school students from Seoyeon High School.

Lee Ha Min appears like a bright person, but there is also darkness within his mind. Han So Mang is a warm-hearted person, but she is also quite timid. Lee Jae Min is a popular student with a painful past. He is kind to everyone around him. Yoon Bo Mi is a sweet, model student. Choi Jin Young loves playing games. He can seem unfriendly and has a delicate personality.

~ This story is also about time travelling
~ The protagonist fall in love with eachother
~ They change their future
~ Interesting storyline
I personally think these shows are quite similar as they include same genre

Its similar as the male lead is in the entertainment industry. Male and female lead went to the same school, grew up in the same neighbourhood. The height difference. The difference is that uncontrollably fond is melo, sad and tragic , lovely runner is cute and time travelling but also sad and some type of tragic.
