fsr i often think about this webtoon and i want to read it again

i dont know if i'll be able to find this webtoon again but its about a guy and a girl being friends at first and they get to be together in the end. i remember that the guy went to the military. i think it has to do with a name sora? im not sure or something orangey about it idk for some reason im associating it with orange. i read this prob back in 2018? can someone help meee i've tried to find this webtoon for years and i've checked my webtoon app history, it was no longer there
