All,
Simple question, hopefully. I've researched extensively on the internet and the consensus I have seem to come up with is that there is no real rule to this. Anyway, wanted to throw it out there to get some feedback from the real masters.
There is a girl, that I believe likes my brother quite a bit (she's giving all the signs: touchy feely, always wants to hang out with him, text messages him everyday, etc.), and she has begun referring to him by name-kun. He is one year older than she is, so it clearly isn't the older person referring to a young boy kun type of usage. Nonetheless, since Japanese suffix use is so important to the relationship of 2 people, I wonder what the meaning of this is.
I gather that name-chan would be even more intimate, but I wonder if in many / some / most cases this rapid switch (they have only known each other about 2 weeks), is some sort of indicator in her interest in him.
Thanks in advance for any insight you might provide.
