You should read the brothers story
The little brother has a story?
Yea it talks about how the event traumatized him

Oooh thanks! Will have a look at it in abit, currently on the last few chapters of The ghost's nocturne (￣∇￣") will need something light to read (before bed), after seeing all those curses, malevolent spirits etc ╥﹏╥
Little brother's conversation with Liam was creepy, didn't seem like he was "innocently" scarred by the event like Oliver would like to believe. But i'm glad they didn't explore it further, could do without a crazed incestuous storyline.
I don't get why still choose to opt for that "family can get affected too" omegaverse. The majority of omegas suffer enough already, with family BS, why add SA to the mix #－.－)
