The Ramparts of Ice

After her classmates run off in fear, Koyuki makes faces in a mirror to figure out why everyone finds her scary. Suddenly, a boy sneaks up behind her.

To Koyuki's relief, Yota comes to her rescue. After their initial study session, they grow more comfortable with each other — which unsettles Minato.

Bothered that Koyuki still has her guard up around him, Minato tries to make small talk. As Miki grows suspicious of his intentions, she confronts him.

At Miki's prodding, Minato clarifies his interest in her best friend. An unexpected visitor triggers Koyuki's bad memories, leading to a harsh outburst.

Koyuki mulls over the tense exchange in the infirmary. After Yota clears the air, she tries to have an honest conversation with Minato for the first time.

As winter break ends, the usually calm Minato begins to realize his feelings are changing. Miki notices how close Yota and Koyuki have become.
