Inu x Boku SS, Volume 3 (Inu x Boku SS #8-13)

The residents of Ayakashi Hall decide to make a time capsule and bury it on the grounds, so everyone writes letters to their "future selves" to be included within. As Ririchiyo composes her letter, she reflects on her time with Soushi, realizing how much she has grown with the fox at her side. But when those heartfelt feelings are accidentally delivered not to her future self but to Soushi, Ririchiyo's budding social skills will be put to the test! Is she ready for a face-to-face confession of her true feelings?!
