A review by kricketa
Fruits Basket, Vol. 10 by Natsuki Takaya

4.0

...the sohmas and tohru are still frolicking happily at the summer home: swimming, catching stag beetles (??), fighting, so much fun! then we find out that the kids' homeroom teacher, mayu, was best friends with kana, hatori's ex-girlfriend. she had her own thing for hatori, which shigure picked up on. he decided to cheer her up by dating her, but we know how that ends. hatori comes to pick up a book and sees maru for the first time in a long time.

back at the summer home, yuki develops a fever from swimming too much, and tohru worries. then akito arrives and everyone except tohru and kyo has to go welcome him. yuki, having already run into akito, wanders in the woods, mumbling to himself about "opening the lid." tohru finds him and then....

well, i'm not going to spoil it.
