Bugbear welcomed me at the very beginning of the game before I went into the dorm. As it was my first playthrough, I thought this happens every time you start the game, turns out this was not true. Since he was the first person I saw, I decided I'd try to get into his route, and and interact with him - pretty much failed (either unable to find him, OR I do meet him, but without any dialogue options). After checking the game guide, I realised I was super close to dying :') I'm actually more surprised I didn't die with the amount of times I saw the lines :')
