"Do you remember Kii-chan?"
"Well, actually we met at a cafe where she works, and we've talked after that some times,
and she's been a mental support to me recently. during these hard times in our family, etc..."
I just hate this shitty writing, when people lie about stupid things, and clearly he doesn't have a poker face.
The lie is just a ticking time bomb waiting to blow up, and to make a big gap in the trust between father and a daughter..
