will likely lead to sexual addiction.
Father should be ashamed of making creating a dysfunctional person who will take years if not even to live healthy.
He has major issues, probably also lived in unhealthy life and absolute rule of hierarchy of the "family", this proves his violent outburst on Saito, he also has to keep a charade as a head of the family he probably never really were.
Oh well, at least now they had "permission", but 10 years till their "hormones" won't effect their judgement is outrageous.
Congratulats on sober sex at least...
