Yes during a funny conversation cheran mentioned like "45 mins agiyum dress matha pona em pullaya kanumeanu poi patha..kavin pudichu mokka potukitrupan"
He used the word "en pulla" very casually... For sure it came from heart i felt.
Even I am feeling that their bond is very genuine .. he is very protective of los...at the same time he is not controlling her also .. he is respecting her personal space yet stood by her in all through the thick and thin..
