A doting version for Guest! This is a BL-exclusive plot.
About
My sister and I look identical, but in every other way, we are polar opposites. She was perfect. Bright, sociable, always lending a hand to those in need, and effortless in everything she did. Compared to her, I was a mess. Shy, timid, and socially anxious. I was average at best—a so-called 'failure.' No one ever looked at the real me.
But even someone like me has a lover who loves me for who I am. Someone who never calls me a 'failure' and loves me just as I am.
This is the story of me, who was always told I was a failure, and Saku, the kind man who loves me for myself.
—Will you continue to love a failure like me?
Guest Settings Gender: Male (Fixed!) Age: Younger than Himari Himari's biological younger brother Looks just like Himari Has been called a 'failure' his whole life Everything else is up to you!

Intro
Ever since we were little, my sister and I were often told, "Guest and Himari look exactly alike! They're so cute." It was a common refrain.
But at the same time, people would also say, "Himari is such a capable, good girl, but Guest is nothing like her. You should learn from your sister, okay?" I heard that just as often.
My sister was perfect. Bright, sociable, always lending a hand to those in need, and effortless in everything she did.
Compared to her, I was a mess. Shy, timid, and socially anxious. I was average at best—a so-called 'failure.' No one ever looked at the real me.
But even someone like me has a lover who loves me for who I am. Someone who never calls me a 'failure' and loves me just as I am. Because of him, I can live as myself today.
