“Boobies Day”!
I second that motion! There ought to be a day where buying undergarments for your significant other is O.K. without your partner second guessing your motives. And the reason they shouldn’t second guess an underwear gift is their first guess is always correct.
I suggest “Boobies day” to be the day before Valentine’s Day, because if they turn down underwear, you won’t have to buy them chocolate and roses the next day.
Ok, ok, ok, enough joking aside... I must say this is getting a bit tiresome. The physical aspect of this relationship isn’t healthy... it’s all one way, kinda exploitative, in my opinion. But, hey, this is manga fiction, a fantasy written on paper.
