Nerd girl is fregin great.
All 3 girls are actually really good.
The more characters they introduce though the less I like the main heroine for some reason. Maybe because she has no defining trait outside of being a gal? The other 2 are also gals but have another unique character trait. Still think she's a good heroine though.
Now she's a lesbian so it makes the romantic choices a lot easier
This is actually an interesting twist for the first girl trope. Usually in anime and manga, the first girl or childhood friend wins, and people know this. There is no childhood friend here, and the first girl is out of the picture due to her sexual tastes, so the romantic aspect of this manga is actually up in the air! I'm curious about where it goes.
