The original has a big age gap, top is younger by i forgot how many years but by the time the bottom went to army the top is like middle school and the story resolves around this "hyung always treats me like a kid!" And "is the love i had for yun oh is brotherly or romantically?" type of theme (Not related by blood or anything btw)
The same age AU is like a fun take if the big age gap didn't exist between them and show how yun oh would still overthinks about his feelings and distancing himself from haewon
They have a 6 year age gap, from what I remember the top is 21 and the bottom is 27
seems interesting enough, might give this a go. the age gap isnt the worst ive seen, but the side story name is pretty(i dont know if i want to use the word funny or surprising or something else) out of context
i was looking for some bl to read and i stumbled upon this(havent read this) ..what could POSSIBLY be the context of the side story being called same age au
