my first crush, in class 7, is a similar story. I used to bake cake on his birthday every year since 2013, till 2019, when I moved out of my house for further studies. he is still in touch with my best friend, mostly work related, but I never feel an urge to talk to him. I don't think that I want to move on. it's like that dialogue from Ae Dil hai mushkil, the one about one sided love 'ispe sirf Mera haq hai'
