I think it's the best for me to back away, before any misunderstanding happens, right? Nahh, it's not that I won't be friends with them ever again. For me, once friends, always will be friends *unless one of us did something unforgivable. Because friends for me, are everything. I would die if I don't have friends.
Back to the topic, imagine if you have a girlfriend/boyfriend, and they seem to be so close to a (different gender) friend, you too will be piss off, right? Don't lie to me, I knew it. You would mad, wouldn't you? Everybody would.
So, keep a distance between you and them okay?
*I'm just reminding
