It has created a bond with my heart. I started watching it when I was around...i guess 10-11,that time I didn't understand anything 'cause I was watching it just for fun. But, 2 days ago, I downloaded all the parts from prime video and watched them. After every part my just felt like it was wanting more Harry Potter and I wanted it to never end. It has literally created a bond with me. I don't know what it is?, but yes everytime my heart is like beating twice the normal speed whenever(I don't want to but it comes to my mind any how) I think about it.
