Story you loved but can never reread

Whats a manwha/hua/ga you read and loved reading but can never put yourself through the experience of re reading it again, for me it’s Radio storm and truth or dare, for radio storm I literally couldn’t put it down while reading it and even with the happy ending I felt like a piece of my soul was gone like I couldn’t think properly for DAYSS and for truth or dare the plot twist was so sick I wanted to cry and can never put myself through it again
