I noticed that too, but if I want to bother with it, I can set love day (and even call it Valentines day) anywhere I want in the calendar.
Valentines day tends to be overrated to me anyway irl, despite being an inveterate romantic given the chance.
Obligatory romance is a self-contradiction and I always wonder: is it better to just agree that Valentines day is a bananas contrived holiday for getting yo eat candy in school and put pressure on people to buy flowers, cheap chocolate and so on? Or is it best to try to do something genuinely impressive as a show and declaration of love, lest my SO feel let down if I don't?
