I’m sure many rich folks get ripped off by their employees. But let’s be realistic. The ones who do rip them off have some sort of access to their money. Assistant? Accountant? Sure. Gardener? Probably not.
Shohei isn’t some single guy living with his translator in a luxury bachelor pad. He has a wife. He probably has an accountant. He might even have a personal assistant. (It is LA, after all)
To think his wife, accountant, assistant, and bank all didn’t notice these transactions? And the one guy with complete access to his account was the guy whose sole responsibility was to translate languages for him (which is not a financial thing).
The more one thinks about it, the less likely Shohei appears innocent…
