don't know if it's this one but you can try. you just need to go to this line and set the last part to true if it isn't 
I personally never gave money to adrian for his trip to japan (even the variable for this in my save is on false) and i can go to japan just fine. I did told him to stay and chose the sharing route with anna, so if setting [rid 2013] "adrian-will-stay-start" on true didn't work you can check my first post on this topic about [rid 2265] "anna-will-seduce-adrian" just to be sure it also on true
