My Weird Roommate

An alien, a vampire who has lived for hundreds of years, and a werewolf who was raised by wolves went to college together. The fourth roommate in their dormitory is a human. In order not to be discovered, they all try their best to integrate themselves into the life of human society. However, their human roommates discovered their unusual secret from the beginning, but because their daily lives were so joyful, they still felt that their acting skills were perfect. ——Via Snowodin Intention:
