It's kind of like the John Smith of Irish names
First off, I'll just get the serious stuff out of the way. I think part of living with other people is about respecting each other and taking an interest in the well-being of those around us. So whether my music's too loud or we need to both do an emergency bathroom cleanup before a girlfriend comes over or anything more serious , all we need to do is keep the lines of communication open and I'm sure most anything can be taken care of.
Generally, you don't have any syntax or grammatical errors. I really love the "Japanese" part because it really pique my interest to get to know you as a person. The "respect each other" part really show me some of your values.
As for the "talkative bits," I feel like you're rambling all over, which is the opposite of the image you want to convey. You've already caught on to this, but I suggest you give some succinct examples or delete that part altogether since you're already convey how unique you are through the "Jap" section. Maybe you'd want to add on to the "Jap" section about why did you decide to adopt the language or stuffs that further develop your personalities.
Good luck! If you have some time, look at mine.
