It's when u have a best friend that is rlly like I mean rlly close to u and u guys talk bout everythin and u have fallin feelins for them, so u have a crush on your Best friend and your just to shy to tell him/her bc your scared either be rejected or just will be awkward, so wat u do is that u make them happy and be funny around them and just do alot more other things. And u or u can take pics and vids for funny memories or just any memory bout both of u or just him/her
When you see them as just your partner and then some event happens and you realize why you had crush on them in the first place. When that happens, you form a crush once again on your partner.
