Species 1: Everyday Life with a Lamia

Plot
Early in the morning, Kimihito Kurusu wakes up to find his extraspecies guest, Miia, sleeping beside him on his bed. When he tells her that it is morning and that they should get up, Miia says that she needs five more degrees before waking up. Kimihito then asks what she is doing on his bed, to which Miia says that she couldn't warm herself up because it was too cold in her room and says that she went into his room to have him warm her up.

When Kimihito decides to get up and make her bath to help her warm up, she grabs him and pulls him back on his bed and cuddles him, bringing Kimihito's face on her breast as she falls asleep again.

Differences from the Manga
Chapter 1: Chapter 2:
 * After telling Kimihito the reason she was on his bed, Miia says that Lamias are cold-blooded, but in the Manga, she says that she is a Poikilotherm instead.
 * After Miia reaches her climax, the screen simply goes white and moves to a scene where Miia is about to leave Kimihito's bed, whereas in the Manga, after reaching her climax, she lets go of Kimihito before leaving his bed.
 * After Kimihito turns the shower on with cold water, he tells Miia that they can take separate baths since they are not in a hot spring. In this episode, he says this as he heads for the door and leaves, whereas in the Manga, he says this in the door as he leaves.
 * After exiting the bathroom, Kimihito has a nosebleed again and repeatedly bangs his head onto the sink. In the Manga, however, he repeatedly bangs his head on the wall.
 * When asking Kimihito if he and Miia did anything prohibited, she simply asks if he did "it" with her. In the Manga, however, she uses the "f" word to describe the action.
 * After Smith playfully teases Kimihito about him being easily seduced, Miia grabs him by his neck with her tail, whereas in the Manga, she had struck him with her tail.
