Synopsis:

A devastating accident lands Eunha Seo in the hospital. Mysteriously, she wakes up 12 years younger in her 22-year-old body. Life has given Eunha a second chance, but this is not the life she remembers. Memories blur with reality as she navigates the unfamiliar friendships and romances of this parallel time. Like a surreal game of "what if?," Eunha is torn between the excitement of a new past and a longing for the life and love she once had. Will Eunha ever find solace? Only time will tell.

I absolutely love this manhwa, the mystery behind her situation is so fascinating and I actually don't know who to ship her with because the MLs are so likeable (╯°□°）╯︵ ┻━┻ (with the exception of her past bf)
