Hey guys sorry for the wait, you see I was taken hostage but I managed to escape...
Ok really, I did go to visit the elusive "mu soft office." I checked 2 possible addresses because the way it's shown was not very clear. Neither of the name plates matched, but I decided to ring the one that was most likely correct not expecting anything but someone actually answered.
It was a young woman that came out to greet me. I asked her if he lives here, but she said no and that she doesn't know him. I just explained that I was trying to find an old friend and wasn't sure if the address I had was correct or outdated. She pulled out her phone to check with her own map and I told her the address. I told her a couple times and even showed it to her just to be sure (I had to read it for her because it's in English); and after a while, she said "oh, it's true" to this supposedly being the right address. She explained to me that she was a sort of gardener and that this wasn't really a house but a business place which made sense to me if it was previously mu soft office. At this point I just thought he was a previous tenant and moved somewhere. Thankfully this interaction didn't ever get awkward, after talking a while I just thanked her and decided to give the gifts I brought with me to her since she was super nice the whole time. (I brought a bunch of sweets and a sexy figure btw, and no I didn't give her the figure lol I kept that hidden)
I was expecting office mu soft to be at least a house or building, but it was after I already left Kyoto when I found out this address wasn't right, and the 100% correct address after doing more research. I remember walking right past it... it had no name or sign or anything on it... office mu soft is actually a very old, rundown micro one room apartment. The building is for men only and uses a shared bathroom. Yeah so, unless he's moved on to better conditions and things and just hasn't looked back at mu soft, I have a feeling he's most likely passed...
Unless someone else decides to go there before me, I'll have to properly confirm if he's there or not whenever I'm back in the area because that was quite frustrating to find out lol. Of course, I'll make sure to post here again if I do.
tldr: mission failed, we'll get 'em next time
