Remember, the best things come at a risk.
And I mean, even if that friend didn't feel the same way, even if it made things feel kinda awkward, if it's a good friend I doubt it would ruin the friendship. If you're a good friend I don't think they'd just push you away completely because of it.
May make things awkward, yeah. They might need time to adjust to it if they don't feel the same way.
Of course this is just assumptions, nothing is ever certain in this. Who knows how they may react? But I'd think if that person really likes you as a friend, it's unlikely they would let that completely ruin the friendship. And if it makes things awkward and they don't want to talk to you anymore, just give them time. Maybe they'll come back later once they've cooled down.
In the end, it's a risk you may have to take, or not.
