It’s either a yaoi or shouen ai where two guys are forced to married, except one of the guys has actually been raised as girl since the mom really wanted a girl have having only boys. The both parents and the husband know it’s a guy, and both moms arranged the married together. The “wife” even goes to an all girls school. I also remember in a particular scene the wife never wore pants before so the husband buys him his first pair of jeans.
