People say you'll see ghosts if you walk a lot at night. Could it be that I had really seen a ghost, how could I take a man with amnesia home to make myself angry? I, who usually live frugally, paid several months' salary all at once for him. Yes, I admit that it is also for my own vanity. But... Even though someone saved me, it doesn't have to be so cool. After all, I've taken you in for a few nights, right...
