I mean the guy knew Laajo was not ready to face these people and instead of sticking around with Gunja to help prepare her for the evening, he went out to "hang" with his friends. Gunja did her part and made Laajo presentable but Nikhil should have also stuck around and helped her with regards to how to behave/act/mingle at the party. Instead he just kept getting upset (mind you I understand with her behaviour) but he should have at least gave her a heads up before bringing her to the party...
