Erm it's a bl manhwaa, where the mc has a childhood friend. And they both got into a bus accident due to a malfunction in the bus. The mc remembers the ml, but the ml was a different person. He's almost like a new person. They both met again as a highschooler. Where they both unraveled the ml's past and old body... PLZZZZ I NEEED IT, I REMEMBER THE PLOT, BUT THE NAMEE
Reminds me of this but maybe not

Hello!! I'm looking 4 a manhwa with NO ROMANCE, nor a HAREM. Just pure action vibes and maybe thriller. The last time I read, it had romance it in, and I didn't enjoyed because it WAS too FORCED • ‿ ,•
THANKK UU!!
Excuse me for my bad grammar, english isn't my native language, although it's my first. (/TДT)/
