With age and experience I've learned that you don't really need to put something like that out on the table. If the feeling is mutual, then a romance will most likely blossom on it's own. As friends you'll find yourself in situations where you interact, and if both parties are interested, I would imagine that the chemistry would speak for itself.

ITA with Aya. If there are mutual feelings then some kind of "relationship" is bound to develop.
It's really not necessary to make things uncomfortable by voicing those feelings.
I've had very good friends confess their love to me and although it was very flattering I was very uncomfortable with it because I didn't return those feelings. It put a strain on our friendship for a while.
