This was a cute chapter.
Totally made me remember elementary school too, since the girls usually would each have their own cute spiral journal/book thing and we would fill in each other's books and even exchange cute papers. Just as the manga depicted, it's something kids do, but it's cute that...
I think dude's just teasing him, cause look at Haruto's flustered face and reactions XD
Hope he won't eventually fall for her or something tho
Thanks for the update ^^
