1 truth after 99 lies sounds like Arata considering how much bullshitting he's done till now. He's a pathological liar.
99 truths after 1 lie sounds like Shinju, she really doesn't need to lie much to manipulate people (hiding info is her thing).
Pages 15 and 16 make it look like Shinju has perfect teeth...
I'm not gonna lie, I'd be easy to fool in this sort of situation. Just hearing her talk about eating rice and canned goods only, staying in the corner to stay out of the way... My heart immediately hurt.
I'm a sucker for sure lol
