I read this last yr. so I don't remember everything.. but from what I remember, jua was hurt in past cz of gun. so gun feels obligation towards jua. jua is the most important person to gun just like how junhyuk's got the 1st place in hanmi's heart. it's more than just love.. ugh I'm not good with words.. hope it helps ┗( T﹏T )┛
yes they had that kind of feelings for each other! it took me a loooong time to realize that because i'm too innocent but there are lots of implications that they did felt like that (for example when they were in the infirmary and the younger leaned over the older and the older blushes. how he feels jealous when the younger has friends, how at the end he admits he feels the same way the two main characters feel) i feel like the author wanted to make them canon but couldn't (because they are blood related and no one made THAT before) i don't ship them but it's kind of implied that at the end they end up together because the younger follows the older to university and cooks him
meals, etc.
i spoiled myself by reading chapter 121 and wtf? does jua like gun in a romantic way? aren't they brothers though? what does gun feel about him? i am so confused
