부빙 (浮氷)

Mido is a new Android that resembles humans and has a human heart. Mido desires to get out of the confines of inhuman experiments and to leave where no one can find her. Mido is like an elephant tied to a stake. She transfers to Sira's school for a beta test while she cannot escape the lab freely. Through meeting Sira, a new being she has never encountered before, she realizes that she can go anywhere if the two of them are together.
