Spoilers mam/sir♀
So... the raw been going around before the official English released (it's not a global release so each languages updated at different times), and the majority of korean readers were like, "I'm glad in the canon one, haekyung is the older one...."
I didn't really follow this manga so i didn't even know there's an AU side story, and since I'm a sucker for age-swap or age-reversal AU, my friend said i need to check this out... And our first ever discussion was like, "yeah... I see why the author made woojin the younger one"
YALL ARE MAKING ME CURIOUS OMFL
yo i read the au’s raws… let’s just be grateful haekyung is the one older in canon -.-
i can’t even say the au’s ending can be true otherwise cuz it would def happen T-T
