Shamiko excited about sleeping together with Momo? That's new and welcome.
Momo bothered that Shamiko is obviously hiding something from her and Shamiko embarrassed that the conversation isn't with the 2 of them alone is more of the good gayness that I was missing for 2 months.
That being said, as good as dream-diving is for the end of a volume, is it really necessary? The point of the previous chapters is that Momo and Shamiko were gonna be open with each other about everything in their pasts and with the current situation only Momo will reveal her past, she still won't know about Shamiko's. This is one of those cases in which simply having a talk about their mutual thoughts and feelings would have been more beneficial to them.
Momo apologizing in advance really picked my curiosity, she said she had no idea about Joshua back during the box reveal, so I wonder what she means.
