I talked on the phone to a long time friend of via kakao for the first time today (which is weird since we've known each other for about 5ish years) and it was actually much more comfortable than I thought it'd be! I'd love to call more friends via line or kakao to chat with them so if you're a friend of mine there (or would like to be) and wanna call me shoot me a message first and I'll call you when I have the time :D
