水野 真一

本作的主人公。 没有特别出众之处的普通少年。 和四叶是从小时候起就是所谓的青梅竹马关系，一直把她当作妹妹看待，但最近感觉到这正在变成对异性的爱慕。 虽然觉得日益美丽的四叶和平凡的自己可能不般配，但唯独对四叶的爱慕之情，他自信不会输给任何人。 其实四叶也对真一抱有着无以复加的好意，是两情相悦，但因为两人在恋爱方面都太迟钝，所以没有察觉到那份心意。

摘自本作简介中该角色的段落

An average lad who doesn't especially excel at anything. His childhood friend Yotsuba is like a little sister to him, but recently, he started seeing her more as a woman. As Yotsuba becomes prettier by the day, Shinichi believes that an average guy like himself is not a good match for Yotsuba, but he's confident that he loves Yotsuba more than anyone else. Actually, Yotsuba feels the same, but since both are ignorant and late bloomers when it comes to love, they have yet to notice their feelings for each other. [Translated from DLsite]
