Actually, Jun almost never talks about his family, so that's really the only area where I kind of stretched the limits of what we knew (besides this being, you know, an AU :D). But we do know he lived with his parents and a sister and then moved into an apartment. They all seem super sane. ...but in any case, Matsujun's neuroticness seems to come from a Mom-side, so that's what I did. ;)

lol yes, poor Matsujun. Thanks for reading! ♥
