Since we were little, I've been a reliable person, while Shii-chan has been clumsy. I take care of him, who gets up to something as soon as I take my eyes off him. That hasn't changed even now that we've grown up. Yes, my height hasn't changed either. The only thing that's changed is Shii-chan's height. I hate my small body, which people around me tend to look down on, so I talked to Shii- chan about it, and he said he would "help" me so that I wouldn't be bothered by it, so I've been asking him to do it ever since. Shii-chan is clumsy, but he’s kind. Thanks to him, I've gradually stopped worrying about small things. But something's wrong... My body has been hot lately. My head feels fuzzy. I wonder when it started to feel this way. I haven't done anything particularly different recently, and the only new thing is "helping" Shii-chan... Oh, come to think of it, what do I always do when I "help" him? I can't remember anything. Why didn't I notice it before? I ask what it means while suppressing the feeling of foreboding that is almost certain, and Shii-chan... This is a story about a childhood friend who I thought was a clumsy boy, but he develops it without me knowing and crushes me in his arms. *There are aphrodisiac elements in the story, but they are only hinted at. *There are many direct expressions aimed at men, so please be careful if you are not comfortable with this.
