Fruits Basket vol. 18 / Natsuki Takaya / 196 pgs.

This volume finishes the Rin / Haru story arc.  Rin gets caught trying to discover a way to break the zodiac curse.  For punishment she is placed in an isolated room and is not given any food or water for days.  When she is released she is weak and in a delirious state.  Haru figures out why Rin has been so distant and broke up with him earlier in the series.  What I like about this volume is that Haru really thinks about what it means to be in a relationship and that when you love someone you try to continually understand the needs of your partner.
