MCY-0202 Sister-in-law, please don't.

That night, coming home in a drunken state, the sister-in-law walked straight into her brother-in-law's room instead of her own. And then that night, a lot of emotions happened: there was joy when the two talked about the neighbors around them, sadness when the sister-in-law said her husband often went to work and didn’t return until the next morning, and... pleasure when the wife got so drunk that she couldn’t tell whether she was with her husband or her brother-in-law anymore, and so... of course, both were pleased.
