It's nice to see Mitsuki taking the initiative to reach out to Aya. Of course, I suspect that the ensuing conversation in which they make up* will probably be long enough that it takes at least two chapters.
*Of course, I wonder if "make up" is the right word, since they were merely acquaintances who met up by chance at a place Aya happened to frequent. As such, this is part of the reason why I'm relatively sympathetic to Mitsuki for not realizing how emotionally invested Aya was in their relationship.
