The 0.4a update let's you do both.
I found a bug.
There are 3 possible routes (1 with a small bug)
Route-1 => If I choose only Ash, Viktoria is blocked.
Route-2 => If I choose only Viktoria, Ash is blocked.
Route-3 => If I goto both then there is a bug. Doesn’t matter where I go first, Viktoria or Ash, Viktoria is blocked anyway.
After the interview with Ira, if I choose
=> Route-1, MC does not ignore Ash, and take her for breakfast, and flashbacks from previous night.
=> Route-2, MC ignores Ash and go alone for breakfast, a message from Viktoria, and a choice If MC is interested in her or not, also flashbacks here.
=> Route-3, same as route-1 but no message from Viktoria, she is blocked.
Dev, kindly fix this bug if you can.
