Damn, I've been crying for the past few chapters, but knowing it's over makes me want to cry some more.
It's been over 10 years now, enough time for me to graduate high school and then university but seeing Matsuri graduate made me way more emotional than those two combined.
Really goes to show how a beautiful story can touch you.
I wish the author, Matsuri, Miss Sunflower and all the other characters only the best.
