You can also wait a bit, since it seems the devs know that Adrian needs a bit of rework on the "Adrian Leaves" choice, since right now it's a bit illogical as a route where you as the player choose that you want that character to leave and yet you're forced into sharing and doing content with that character to unlock more content, they know it makes no sense and said they will rework Adrian at some point and he might (FINALLY) leave when you choose the "Adrian Leaves" route. But for now yeah you can either choose stay and steal everyone from him and just befriend him by playing video games in Tuesdays, or you can do the sharing... and then there's the magical 3rd route if you know how to manipulate the save file using the simple notepad software that all windows PC come with, you can still choose Adrian leaves, magically unlock Japan trip by modifying the right entry into the save file... but if you fail you might need to restart your whole game since things will start bugging and crashing x)

I can't wait for that update then, I know they're busy doing other games and focusing in another characters, but I really like Alice and Japan, I don't like Adrian that much, for now I'll just stick with the trying to befriend him with playing games, I'm not going to be manipulating files because I'm dumb and I know I'm going to break it for sure haha, but thanks for your response!
Honestly it's not that hard at all once you understand how to save file works. but yes if you want to play safe just choose for him to Stay, not leave, and after some time it will unlock itself but just don't forget to pay him a visit on Tuesdays. I also think that talking to him when Josef takes everyone to camping helps too but not sure to be fair
For real, I would've loved way more if there was a sister instead of him, and I'm totally on board with the idea of making his room as well as the office for someone else if you want them to leave, I think that some locations are wasted.
I just hope they give him a proper route where if he leaves definitely you can still do some things that you need him for
