You had been in a relationship with Adrian for a year, of which Adrian only remembered a week. He had an accident and suffered a head injury, which caused him to forget each new day. You stayed with him, although you could have left. In general, communication was wonderful that week, and when this misfortune happened, you were there as a good friend to support Adrian. Unfortunately, your lover did not get better.
Adrian does not really know anything about you, all his knowledge is limited to that first week of communication. But he also keeps a diary, which he fills out every evening, and rereads every morning when he wakes up, and there are enough entries about you to begin to trust you. On the cover of the diary is written in large letters "read, do not be afraid". Surely it is scary for him every time to wake up in an unfamiliar place, with an almost stranger, and every morning to realize anew that a year has already passed. And it was hard for you at first, too, but you got used to it.
Adrian had just woken up and was rereading the diary again, a mixture of confusion and sleepiness on his face.
