To be honest, it gets somewhat out of place when at the drop of a hat Samar tries to or hugs Nandini. I mean we get he likes her, loves her blah blah.....but boy, it's one-sided still !!! Neither has she reciprocated or consented. If she hasn't objected, does not mean she has consented.
He just barged into her house forgetting certain etiquettes. Every time, he kind of says something that clearly puts her in a fix or makes her uncomfortable. Now since he read ..."samar n whatever...." was in her diary (obv without her knowledge !!!), something has made him believe that "may be she likes me...." But STILL -----> She has not given a nod !!!
The only thing I can imagine she writing is that she was able to move on from her past coz of him or may be his friendship. Or even if it is love, you don't hug a girl every now n then unless youre a couple. May be different views you guys can have
