Sure, but because of this the whole thing feels like the author is talking with himself. The characters don't really feel like they have a different "voice", it's a bit hard to explain.
Gotta admit Olivia made a pretty hot declaration. But this doesn't feel like the kind of manga that is gonna have a single winner, if anything Machino will try to make everyone fall in love with everyone so they stop competing for love. Though it'll be fun now that Olivia gets serious in her...
This author really really wants to do an onee-loli manga in which the loli is in elementary or younger, there have been plenty of hints besides this chapter, I hope they do it someday.
