Marika’s face! HAHAHAHAHAHAHA
Priceless.
Considering she’s the only one that remembers that time fairly well of the other girls before Yui’s arrival, I get the feeling she recognizes her from back then and is mortified someone that can refute her twisting of events is here, now. Yui is older by a number of years, after all, so better memory of the time when they were all together. There must be a good reason she acted like she didn’t recognize Chitoge- at least, I’m fairly sure she must have remembered her, and is intentionally hiding it. She’ll probably keep up the act with Kosaki, as well, and maybe Marika, at least until she gets dragged into the ‘10 years ago’ (shouldn’t it be 11 now?) discussions…
I really like Shu’s reaction, too. He clearly can tell something wacky is going on with this Yui-sensei and the gang.
Also, Tsugumi seems like she might recognize her, based on her reaction, but is having trouble placing her. Kosaki, on the other hand, seems utterly oblivious. Poor thing.
