The AE is even more painful for Jihyun, it's a what if uni where he never screw up, Chiwoo never got hurt and can still play football. I think it emphasize Jihyun's crime against Chiwoo. They only end up together if Jihyun never did all those things.
The bar is so low but I hope Jihwan's just gonna manipulate his way into Soo Young's life not just use force like Gyujin. That guy's completely obsessed, delusional, guilt/money tripping, threating to out Soo Young.
I read chap 39 and we can say the craziness and obsession run in the family, ahem his father ahem
