Right!!! Though in Heonjae's mind he probably thinks Jingi betrayed him first by having feelings for Myeonggi. Heonjae is a lot of things but even he can tell that Jingi also likes Myeonggi and he feels betrayed because Jingi was only supposed to help Heonjae win over Myeonggi. Also Jingi doesn't really tell Heonjae anything try to protect him and does things in secret for good reason so Heonjae often feels left out and more isolated than he already feel. Sad to see the betrayal though.
I'm actually really glad they didn't show the pictures and just vaguely described them. This story is dark, true, but I don't ever want to see anything gross done to a child. EVER. Vaguely describing gets the point across enough.
Heonjae is really going to be in his villain era next season. His own brother??! His brother who has looked after him the whole time? Crazy work.
