That's true his toys from his childhood are no longer in the cupboard, I don't think he has short term obsessiveness though, he probably thought it's time I get rid of them now as I'm a married man and have to make space in the wardrobe for Gopi's clothes as her side of the cupboard is full.
I think Kokila is worried about Aham not paying attention to his work and only being able to concentrate to the needs of his wife. But I think she is worrying unnecessarily as he will calm down when she is out of danger, she came out of hospital that same day, and he was spending nights with her at the hospital, it's natural that he feels attached to her medicine routine and diet etc, when he sees her recovering at home he will concentrate on work, she needs to speak to Chirag to carry more workload at the office, until Aham is fully there.
