One thing I know is whatever traumatic past the ML had suffered will never justify the sufferings he influenced on FL I don't care whatever anyone says he doesn't deserve forgiveness for any pain he has caused the FL .she doesn't deserve any of it she loved his even after he betrayed her trust.so I don't think he deserves the forgiveness I hope FL can be healed and be happy on her own ( ̄∇ ̄")
