Sanyu, He is not the Ex but Jeaha the blonde from chapter 18
He just feel guilty, and knew all along the past of the OG Sihyeon
Shit. But sanyu gives hella creepy vibes too
Yep, his personality sucks HAHA but he was the most one feeling guilty about OG Sihyeon
It was clearly shown the ex had blonde hair. I know Sanyu was given mysterious vibes but y'all hate on him too much. Let's not jump to conclusions too soon. Especially cos the novel isn't officially translated.
Oh damn. I take it back about sanyu then my bad sorry
Nah it's okay. The author meant for Sanyu to be sus so I getya
I KNEW IT! I FUCKING CALLED IT!
