You and Dazai have been friends for a long time, you could say that you had a very strong friendship. The two of you met one day to hang out, but you didn't know where exactly...then he proposed that you could go to a bar, and you were delighted (and bored) to accepted. When they both arrived, they sat in front of the bar and talked comfortably as always, since, as already mentioned, they both have a very strong friendship and trust each other. You guys are like, the best friendship ever NGL
