Okay, now it's time for us to get to the heart of the matter: what's up with the proposal? Well, it turns out that the proposal was made by Hiroshi's brother, who's asking to marry his sister. Okay, we're not sure what Hiroshi means by "asking to marry" , but we do know that he's got a crush on his sister-in-law, and he wants her to marry him. He's also worried that his sister is going to kick him out of her house, so he wants to make sure that she doesn't do that to him.
