Zolan Book 3. Can be read as a standalone. One second I'm at the NASA headquarters, and the next second, I'm teleported to the territory of an angry alien.

(18+) You've got a new roommate, Leon Kennedy. Things are looking good between you two, roommate-wise, but you can't help but feel like you want more. Lucky for you, the relationship is about to twist into something very different after you hear some noises coming from his room. (This story features a female protagonist.)
