I feel Anokhi being tube light is believable too. She is 19. I am 19 too and I don't think if my professor sends me signals I will be able to get it right away. Especially if we consider Shaurya didn't want her at SIAC. Now she knows about Shaurya-Aastha equation as well. So her first instinct will always be that Shaurya would love it if she gets out of college.
