Nothing angers me more then when parents ruin their child's future because of their selfishness/jealousy/greed. Whatever happens I hope Eunyung knows it's not his fault! People do crazy things to get their parents to love them, even if those parents have hurt them really badly, especially in cultures like Korea where elders are heavily respected and people are expected to obey their parents like gods. He's still young and subconsciously looking for that type of validation.
