I've been married to my wife Ai for several years, and recently Ai has started to worry about her body shape, asking, ``Have I gained weight?'' She doesn't listen even though I tell her that it's okay because she's thin, so the two of them end up signing up for a trial membership at a personal gym. In the end, since I'm not good at exercise, I quit immediately and my girlfriend and I ended up being the only ones going to the gym. Just being alone with a muscular trainer makes me anxious, but my clothes are becoming more and more revealing each day.
