I would order melon cream puffs and milk shake... probably.
Well, Miku resting presenting her assets right under Sou's nose is certainly something to behold. But Sou should be at least used to seeing something like that... Kaede already did the same during class and Sumire or Akane will definitely do that at home during meals even if we don't see it.
Honestly, Miku can be really adorable when she's like this ... now, if only she were less trigger-happy when it comes to violence and intimidation. Still, Kana and Hina who see her behaving like this sure don't believe it. That expression on the last panel.
