I remember reading this years ago and just found it again. I wish it had another adaptation, like a live-action series. Naozumi, still struggling to get over Sana is sad, but very realistic. He did so much for her. Sana's mom was right, one day she will realize everything Naozumi did and she will cry so much. I'm sure she did. I'm glad Sana is with Akito and they have their baby. Kodocha will forever be my favorite.
he's so pure ┗( T﹏T )┛
