Love it but still have questions

I loved this especially the relationship between Taemin and Woojin kept me hooked it felt natural, also both likeable! But...
-Did no one really give a shit about Siwon? I felt his trauma was brushed over by the other characters?? I wanted justice for him dude tries to help his jealous petty brother only for that guy to ruin his life.
-What ended up happening to the younger brother??
-Also I feel like the other guy (guy who filmed the rape) got away with everything?? He's just as guilty.
