You all won't believe what happened today and can't believe that it was in real life. Was it a prank or was it real in your opinion?

You all know that i go for classes to prepare for exams to get into an MBA B School. Today during one class, the teacher(whom we call DJ) was a happy go lucky kind of person so he was talking about Valentines day and stuffs and he was calling me a Valentine boy because I wore my shrug today. There is this girl in our class named Suhani about whom my classmates have rumoured before that she likes me and she tried to talk to me too but we never talked much as I am shy near girls in person and i never really had crush on her and i didnt believe that she would like me as I feel i am not good looking enough. I turned 23 over a month ago and she also turned 23 about 3 weeks ago. Today suddenly she told the teacher that she tries to talk to me but I am shy near her and rejected her. So the happy go lucky teacher DJ told her to propose me for Valentines Day and she literally did. She asked me whether I can be her Valentine or not. I was shy and blushed and said yeah while blushing and everyone was teasing me for fun in class. Idk whether this was real or it was just a prank thing for fun. I already have a massive crush on this other girl Akankshya who is in a different classroom so I am confused but i am still unable to believe that she proposed me like that in real life and blushed and was shy to talk with her later.
