One thing about Sameer that confused me - he was upset when he found out that Naina was giving him blank calls. Shouldn't he have softened up a little when he realized Naina was giving him support by playing those inspirational songs for him, even though her own brother was also competing for head boy? Instead, he was telling his friends "upar se mujhe blank call karti hai" like as if she was doing something horrible. Did he think she was just playing games with him at that point as well? Maybe I am reading too much into everything! 😆
Also, I don't think Sameer knows yet about Naina finding out about the real thief (Arjun). So far, he has just continued to tell her that he is innocent, but Naina is still protecting her brother. I would expect Sameer's attitude toward her to change when she admits to him that it was Arjun who cheated, or maybe she might convince Arjun to tell the truth himself.
