My stepbrother, Akira, was introduced to me as a high school student when our parents remarried. He is a beautiful boy but shy because he grew up in a difficult family environment.
I've always wanted brother, so I spent time with Akira for his sake, and...... we hit it off right away, and we quickly grew close! 
 
I asked him, "......bro, do you like me?" "Yes, of course." 
 
Our relationship deepened despite a critical misunderstanding. Until finally, I realized that Akira was actually my "sister" and I became very confused....... 
 
"I liked the relationship between us when we were just brothers. But I wish we could be something more than that." 
 
Akira's new approach, trying to make us "lovers" instead of "siblings," has begun!
