Shin dislikes drawing attention to himself and prefers to observe situations. He is often cold and aloof towards his classmates, and Yuusuke's constant pestering irritates him. At first, he treated Maria with disdain, appearing to want nothing to do with her, but circumstances proved otherwise and he seems to actually care greatly for her. He pretends to be "rude" to Maria thinking that his actions would somehow lead the other girls to sympathize with her. In Chapter 4, he scooped up Maria in the middle of the class and declared that he would take her to a hospital because of her sprained ankle, making a scene as they leave. Then, he secretly bought Maria a pair of flashy shoes (apart from the ballet shoes he already bought for her) even after earlier commenting that they looked stupid. Despite claiming that he does not want anything to do with her, he finds himself falling in love with Maria, but there is no way that he'd let the "devil" discover his feelings. It is later revealed his "loner" persona comes from an incident when he was a kid where he "choked" during his large piano debut making the media destroy his image. In chapter 23, Meguro insists he will stand by Kawai Maria's side no matter what happens.
