LOL called it, the Nana translate to number 7. I really like this manga. I love how every character show up in the last chapter, even only mentioned in conversation. Truly good read and encourage me, however small it is, we can change the world, start from our surrounding. There are still room to develop tho, like how he struggle with his post-study choice, but ending it at this timing does also feel perfect...
9/10 for me!
