I found Reiko a bit passive aggressive.
"You forgot Valentine's day, so maybe I'll get married.. how would you like that!"
Emotional blackmail.
Meh. It's fine. Reiko seemed to know that Maki wanted to move forward, but was over thinking it. She just needed give her girl a push. I will agree she should have been more forward about it, but it does make good reading. It gives the reader a moment of tension, and a beautiful romantic resolution.
Adding on, the way op said it made seem like that was all there was to it. When really she was pointing out how forgetting “trivial” things that end up causing relationships to fall apart. Birthdays, anniversaries, Valentine’s, you name it, these happen every year and every so often once in a while, we let these events slip our minds. And yes they seem minor or trivial, but the significance of these events are they’re the chances we get to celebrate the relationships we have with others, and for some people it can be hurtful to be forgotten like that. Just take a look at those dudes from the bar, it’s Valentine’s Day and here they are at a bar when they should be at home spending time with their partners. They even went and admitted to getting something from their wives on Valentine’s, but not put the effort on remembering to do the same on White day, do you think their relationships are great? At some point, the more you forget these things in a relationship, the less effort you put in maintaining the relationship itself, and at some point, they’ll just inevitably fall apart in the end.
