The "(✿´°‿°)つ(╹ω╹🌸)" emote is a combination of two different emoticons, one with a smiling face and closed eyes, and the other with a sad or pensive expression. It can be interpreted as a way of expressing both happiness and sadness at the same time. The "Know my friend" emote may refer to this particular emoticon or could be a separate emote altogether, but there is no definitive information available about its meaning or origin.
