As the MC seems to be half Asian / half Irish based on the model/lighting (at least in the early mid/before the haircut which helped a little) and since we know his dad is Irish. I doubt the model will be retroactively changed to be just Irish, adding some story beats about his mother being of Asian descent would probably work without requiring scene editing or anything.
A few of the time jumps feel a bit disjointed, though if you plan to go back through and add additional events then I understand.
The first interaction with Louise is super odd, and the why on the mc not sleeping could have been shown rather than told later in the chapter.
All in all enjoyable and look forward to more.
