I think Teju's crush on Ruturaj is the most realistic thing in Ghum present season. She's a college going girl so likely a teenager. I've seen Kpop fans going as far as to South Korean in hope to meet their Korean popstar crushes. Teju bechari to khaali Amravati se Nagpur hi gayi thi.
In fact, I think it's Neel's crush on Teju that's way over the top. She is a college going girl and Neel doesn't even know if she has a boyfriend of her own age in college. Still Neel considers her as Aparajita. And Neel otherwise is shown as very sensible, feet firmly planted on ground kind of guy so for him to develop this intense crush over a college girl is weird.
But since they are not showing Neel going out of the way to orchestrate his and Teju's meetings and them meeting again and again is purely coincidental, his crush doesn't go into weird category. And since they specifically have shown Neel as an awkward introvert, and introverts do develop intense crushes and their feelings don't skip from one person to another that easily, plus Tejaswini-Ruturaj-Neel chemistry feels organic, so Neel's delulu seems likeable.
But honestly, I feel in terms of writing, Teju and Ruturaj are the best written characters in this season. Neel would've been way off if it was played by another actor than Param but Param somehow managed Neel not to go into cringe, annoying delulu simp category through his acting.
