Sameer behaves different when he with his frnds n when he is alone

Remember d phone call when naina was playing song to say sorry then he was actually very happy for that.In yesterday's episode she made cake for him with lot of affection but his facial expressions were completely different when munna n pandit r nearby.I guess no one till date have made something specially for him except nanu without expecting anything from him.Even 1 day his mom cooked parata for him to just make him say sorry to his step dad.According to these consequences he should be very happy after seeing cake that too hand made.I think d day he'll loose her for sure he'll remember this
