Japanese TV series

i was catching up on the latest tv series while in Japan. funny stuff. but only in Japan would you get the following situation:

a mother asks her married daughter's colleague if he's in love with her daughter. he eventually admits that he is but asks her if she would let him tell the daughter to find out what her feelings are, as they've been spending a lot of time together. the mother, who's also concerned about these potential feelings, agrees.

next scene, they're kneeling around the table at the mother's place (this is Japan after all). the daughter arrives with her husband and wonders about the presence of her colleague. eventually, they settle down and the colleague, keeping his eyes on the mother, tells the daughter about his feelings and asks her to marry him. the husband looks worried but says nothing.

eventually, the daughter tells her colleague that she has no feelings for him. he apologises for the situation. then the husband apologises to the colleague for having had to go through this! in any other country, none of this would have happened. the husband wouldn't have let the colleague speak (the mother had said he was there to propose), and would surely have punched him thereafter. or something to that effect. no?
