Why do I always imagine that that Rui guy is a hippie? Like can someone explane?

Now when you did mention it.. Well, he's always so chill, more or less happy, isn't bothered by anything. He's giving somehow aura like hippie. But I really like him.

OMG that's so true!! When I read your comment, the image of a hippie Rui just appear in my head.
As to why it must be because he always have this happy smile and we will never see him angry
