The author could have easily taken the easy way out and had Momo fall in love with Seno to create drama. Instead, she creates two people where there's tension because of the FMC at first (at least one sided) but through that connection, they develop their own kinship and understanding from being open about themselves, and accepting each other and move forward without any romantic undertones. It's so rare to see these platonic interactions between a guy and girl that doesn't immediately equate to romance but it's so refreshing when it's done right!
As charming as the main couple can be (and the reason why we're all here), sometimes we need that change of pace with another pairing. Momo and Takada barely met (if Takada or Momo will actually recognize their actual first meeting) but gosh, I am already heads over heels with their dynamic. The observant yet teasing (instigator/triggered), being completely open with each other in a heartbeat. I hope Akinoko releases more snippets or even full chapters about their development since they got me hook, line, and sinker!
