Erthenia

His willpower is low, and he's unlucky.

After giving the guy the happiest moments of his life, Sitri got out of bed (or off the floor, it doesn't really matter) and, in a completely different tone, much more mature and cold, said:
-Not bad for a first time. Listen and remember, Dice. You are forbidden to tell anyone about what happened here. I also forbid you to tell anyone that you are obeying me or to try to find a way to get rid of your condition. From now on, send all your earnings to me, keeping only enough for food and to maintain your appearance. Otherwise, behave as you did before, don't arouse suspicion. And for now, give me your accumulated savings; you don't need them anyway. With these words, the southerner began to fix her hair, adjust her dress, and tidy herself up.
