Aryamaan is not touch in Soha with 10 years

I can't understand such type of family relationships. Aryamaan is not aware of Soha's condition and her disease. But when he heard about her death, without thinking anything he is blaming Manik for death of Soha. This means papa Khurana is only hope now. He may tell everything about Soha and Manik's innocence. Moreover Nyonika's ugly truth in the involvement of Soha's case. This means Aryamaan is unaware that Soha is alive with 70%burning.
