Can it be this https://www.mangago.me/read-manga/cozy_obsession/?
Sadly not but thank you anyways!
Based on the description, I initially thought it was this series:
https://www.mangago.me/read-manga/i_m_the_editor_of_the_person_i_killed_in_a_past_life/
But after doing some general snooping they seem to both remember their past life so I thought this may be the one your looking for (kinda searched hours cause I can’t remember the title and can’t get it out of my head)

They’re latest reincarnation was being a soldiers! But based on what the MC said they always reincarnate during times of wars. (๑•ㅂ•)و✧ hope this is what your looking for!
Yesss that's it KJ omg, thank you so much!
No prob! Happy reading! ヾ(❀╹◡╹)ﾉ~
Two characters constantly being reborn and seeming to die whenever they meet, with one of them accidentally killing the other. It ends with finding out that one of them was killing the other so they would keep being reincarnated and could live many lives together. Both were originally soldiers.
Story begins with MC running into the other and being flooded with memories but the other doesn't seem to remember him and keeps trying to get away from him.
Thank you if you know it! I tried my best to say what I remembered.
