I must say the whole crotch sniffing is the biggest mystery of this series. I still think that can be replaced with a hug and hair sniffing and the story would still be okay as it is but less confusing. Still trying to wrap my head around why the author prefers the crotch sniffing, which audiences can't relate or understand.
On Pg115 where she goes facesitting and say "welcome home," that image is just wrong. It is suppose to be dramatic and heartwarming. But with the whole crotch sniffing thing... it's just not working.
Finally, the scene with Yoshino.... that's just f***ed up. You just don't go that far then tell your partner to get lost like that. >.>
