You EXACTLY know what i'm talking abt.
Idk if you know each other irl but I can already say that you'll be the "we're just friends" ppl while you know there's something else.
Believe me, If there are 2 things i can do well they are:
1 "reading" ppl (online it's a little bit harder but still possible)
2 predicting future, especially ships. In my life i predicted 6 relationships, i never got it wrong
