So about your ike book
Idk if this is correct, but I did some calculations and this is based on my memory btw
So Y/n was 3 when she learned abt porn right? And(assuming) shes the same age as jahan, jahan is 5 years older than mysta bc Y/n said "five year age gap" and mysta is 18, so jahan and Y/n are 23 yrs old. And her brother is 26(said when they found his phone at the cliff) so 26-23 is 3, therefore they have a 3 yr age gap.
So if Y/n was 3 when her brother told her about porn...
Her brother was only 6?
Okay idk what I'm doing
