Man I really love Nagisa. Level-headed, elegant, beautiful and badass woman. She put his happiness before her own despite knowing how she could've made him hers.
A bit sad that they're making it out to be like it's the first time she confesses to him while she already did it (and the first one, at that) during the fireworks festival two years ago.
Nobody, be it her or Yabe, ever mentioned it again, with only Miku taking steps forward. I can't help but think this is a real waste and kind of a cop-out to allow Miku to get ahead of her.
There is no way Nagisa wouldn't have won if she had pushed through while the two others were still students.
Any man would be a king with a queen like her by his side.
