Well this was a disappointing read, tremendously slow, I can't imagine what it must have felt like to read it as it was coming out, they are supposed to be in College and act like middle schoolers, our heroine going from being completely frigid to clueless, she might be autistic.
Kaguya Sama love is war, is much better, better drawn, characters, more progress, funnier and doesn't feel as slow.
If anyone cares, there is a webtoon version that is in color.
