Hijirikawa, that's so nice of you! Where are we going? Ah, are we going to bring Mitsuki-chan along as well? We should, I wouldn't want her to be all alone!

[Because Jinguji is gone and Hijirikawa is the only close friend Natsuki (assumes) he has available for Valentine's Day BECAUSE IT'S NOT LIKE HE HAS A GIRLFRIEND, RIGHT?]
