Thinking about someone and smiling for no aparent reason is a flag. This an adult woman, of course she ain't "crushing" like a little girl lol. she said herself she only saw him as a little brother at first, chill out y'all non believers.
Page 6 "I didn't know his commute went through here". Isn't this implying she knows him already? don't have the raw to compare. It all points out that this is in fact the first time they meet, so i'm guessing this is a mistranslation? dunno.
