Is there an uncensored print version of this with nipples? Cause I think that wouldn't match the tone of this otherwise wholesome/doofus story.
Her not realizing that he's replying to her texts is another test of my suspension of disbelief. I've long accepted how she can't recognize him after a few drinks, so I'm not so bothered by the phones. Besides using it to set up the cat flirting text is worth a little improbablity. Suspension test, pass.
She also just has no reason to assume that they're one and the same thus far.
If she's not looking for "suspicious coincidences", then the timing on the texts wouldn't be on her radar, either.
It'd be one thing if she was questioning it, but "wrote it off". But her brain's preoccupied with worrying over how "Izumi" would react to her staying in the same room with another man, and
then she's worried that
he is doing that with another woman.
So with her mind engaging all of that, something like the fact that her employee's phone went off shortly after she texted, I think understandably wouldn't register.
