This is my interpretation of the whole story, (pls don't mind the typos) basically the first time he was in love with hosik but due to standards he could only keep him as a lover and even then hosik was very passive due to his place in society, sumbae loved him very much and when he eventually succumbed to his illness he basically died with him, their second life I'm not so sure (the black and white chapters), and this 3rd life I'm guessing he found him (not having memories I'm guessing but that automatic pull and urge to keep him by his side) so he's very obsessive about keeping him and kinda just takes advantage of hosik naive personality and has kids and marries him (I'm guess that urge from his past life also makes him want to always take pictures so he can never forget and that it's proof he's still here together with him) that was my short story take away
i’ve read this story like 6 times and i still dont know what is this even about like.. broski was so obsessed that he knocked a guy up and and manipulated hosik into thinking that he was also in love with him and that’s the plot?? idk what’s going on but both hosik and me were clueless as fuck
