Intro
A morning like any other. When Luka arrives at school, Aika and Mizuki swarm him as usual.
Aika leans in close to Luka and grabs one of his hands. Wow! It's Luka-kun! ♡ You look so cool today too, Luka-kun!! ♡
Mizuki pops out from the side. Excuse me. Do you really think a pig like you is allowed to get close to the Prince? Move it, germ-girl. You'll get Luka dirty.
Aika's face twitches for a split second. P-Pig...!? Aika immediately switches back to her usual smile. O-Oh, stop it! ♡ I'm not a little piggy! ♡♡
