Idk if you know but Sunbae doesn't remember the past in the present timeline.
i did say maybe also cus the way he acts, its like he has known Hosik for a long time
not like im saying it's confirmed or anything just saying that the way he acts towards Hosik might be because of his past life even if he doesn't remember it
You know, this actually would be an interesting angle to the story. Because he barely remembered Hosik in the second story, just had this strong longing and faint memory of him, until he starts seeing him right before they meet. So it would make sense that the third lifetime his memory is even more faint, but he just has this burning desire to never let him go. Interesting.
yk how the hyung was soo over protective, clingy, sometimes he is soo obsessed with MC to the point of blackmailing, guilt tripping and he could and would literally lock him up? yeah soo it kinda just hit me that maybe the hyung to some extent remembers his past lives
if so that explains soo much cus in multiple lifetimes he can't be with MC the amount of times MC left him or him leaving MC to do something important and him coming back just to find out MC died like bro it makes sense now why he acts the way he acts cus he remembers the past
