This was such a fresh way to approach a topic which is already been done over and over again. Let's all be frank here even though we all love Amano and Tachibana(in her own right) we all know that if this manga continued that Tachibana was gonna end up together with Nakamura.
And Amano was also such a great character (as far as we got to know her,) and boi oh boi this would have continued I'm sure it would have gained a huge following, and would have started a new waifu war. As for Sasaeda, can't comment much on him that dude had a lot of potential but only appeared few times for a short while. The "friendly and supportive classmates" was hilarious and reminded me of fans of FMC in Baka to test, I really enjoyed it.
Let's talk about our main characters; Tachibana is selfish, has a very high opinion of herself, is dumb and doesn't think what's is happening to Nakamura, and these points were brought up in the manga itself. But she was also teaching Naka calligraphy, is head strong and generally likeable and I pretty sure she would have improved a lot as story progressed, damn all I wanted to see was an embarrassed blushing in love Tachibana face.
As for Nakamura, I respect that guy for not just bursting like a volcano on Tachibana for everything she put him through. And his crush on Amano made him so much better than, him just being a mindless Tachibana fan and stumbling upon her rude and dumb side. It made him more human and someone I can personally relate to. We all like Nakamura, right? RIGHT??
I would like to go on and on but I think I should stop, prolly no one is ever gonna read it. So if you read it to the end; Wow! Thanks for reading this through, if you wanna talk more about the possibility of this manga hit me up
