If you are ever in a situation where you suddenly feel some sort of feelings not platonic but romantic feelings for your best friend or any close friend of yours, and just feel like it's illegal because he/she's your best friend, and if you confess you're afraid of destroying the friendship you two build up together? So you hide your feelings and cage them in your heart forever so you won't destroy your friendship
I say let it free, let your feelings free, you can't cage or hide your feelings for the person you love forever, even if that person you have feelings for is your friend or best friend, if you really like that person than you have no reason to hide or cage your feelings just because you are afraid that it would destroy your friendship
Yes they say "Bros before hoes", and friendships are better than relationships, and friendships are important because it's the bond you build with someone important to you, it's how you two remain close, it's how the two of you bond with each other, I get that your afraid that if you confess all those years or days of bonds and memories of friendship with that person will go to waste and quickly get destroyed
And I get that you're also afraid that when your best friend won't reciprocate your feelings it will get awkward between the two of you, and everything will be destroyed, including your friendship, you two will stop talking, and would basically end things there as friends
But what's the point? If you confess or not you're feelings are still going to get hurt anyways, except if he/she actually do reciprocate your feelings, than that's good, if you won't confess, your feelings will most likely get caged inside you, you will stay as great friends, but deep inside you will be filled with heartbreak, and lonely emotions that you hide alongside your romantic feelings, you will only hurt yourself mentally and emotionally, there's little chance that you would just move on with your feelings and still be friends with her without confessing, but it's mostly forced
I say you confess to her/him with determination and courage, if you get rejected then at least ask if you can still be friends, if she/he's considerate enough then he would say yes, but it'll get awkward though, but there's a chance that it won't get awkward and you two can be friends again without the feelings you try desperately to hide
And if she/he says no to your coffee of being friends, than I guess it's over for the two of you, if she/he accept your feelings thoigh, good for you, you can be best friends, and lovers at the same time, how cool is that!
