Finally Naira realized if Kartik committed a few mistakes she committed many...instead of confronting him for mistrusting her...or leaving GV after informing him about her pregnancy....she chose to hide...she chose to run and abandon them all...she chose not to free Kartik from guilt of hurting her dignity that took away her life...she chose to punish him by staying dead for all...most of all finally she realized that she was wrong in separating Kartik and Kairav for several years...she was wrong in not letting father-son stay together...she was wrong in trying to take Kairav away to Goa...if Kartik and Kairav stayed together from the time she was pregnant or from the time Kairav was born....Kairav would have known him too...he wouldn't hated his father...she acknowledged her negligent upbringing and bad parenting...she tried to make Kairav understand too...Finally dialogue writers woke up from slumber as per their convenience...I always thought Kartik apologized for long long time....he punished himself for long time in that dark room...Naira's apology will never be sufficient enough...but it was...there was genuineness behind her apology that made it sufficient...her effort to unite Kartik and Kairav without any OTT out of the box idea by simply communicating with them...her trying to console Kartik the way old Naira use to do...made it worth watching...Kartik's breakdown his cracking voice and him finally finding solace in her embrace...after longest possible time he calmed down by keeping his head on her lap where his solace lies...Kaira/Shivin were in their element after long time...
