Toshiji had always forgiven her kids. She let go off Romi, by just shedding some tears on her failure in giving good values to him, when he was charged and found guilty of framing Bala's family whose after effects are still there, he had one night stand, he made MMS of Mihika and has spoilt her life, he was also charged of doing accident but all this time Toshiji never took her sword out. She only shed tears and tried supporting and protecting him.
In fact when Param was charged with accident, she went to beg with Amma to withdraw the case when he was found to be molesting Ishita and he still does, where was her love for Ishita then.
Then what happened today, when Raman is trying to protect Shagun who has been framed for accident. Why is she not supporting her child now or lest trying to talk to Raman and find out why he is doing so before behaving in such a way. I found it out of hef character to suddenly ignore Raman, telling him off and behaving so coldly with him.
