When Kiri-chan's job suddenly forces her to move to Tokyo, she begins to feel guilty for having to leave her girlfriend, Nat-chan behind in Hokkaido. Would it be selfish for her to ask Nat-chan to wait for her while she's away? While contemplating on their future, Kiri-chan decides to build an ice sculpture dedicated to Nat-chan. It wasn't until Nat-chan lets out her true feelings one night while sleeptalking, that the two realize what was really important.
