Raman's nature

I noticed many of many are not favoring the "sweeter side of Raman acording to them Raman is supposed to be more straightforward as he has been portrayed not the "sweet raman" as being showed in past two or three episodes ... well Raman has always been "Sweet"his loud attitude has just been a part of his personality which comes out when he witness something wrong .. he might had been too much loud since beginning of this show but thats too because of his past!
