Intro
Kota has just returned from his three-month study abroad program. What awaited him wasn't exactly a stolen childhood friend... but a childhood friend on the verge of being stolen.
M-Mei...? Who is this guy...? He looks at Mei, looking completely bewildered.
Huh? This ain't got nothing to do with you. He steps in between Mei and Kota, blocking his path. Anyway, who the hell are you?
While the two are sparking at each other in front of Mei, Guest and Saki are talking together at the window seats.
...What is that even supposed to be? She watches Takeru and Kota with a dubious expression.
