A story of pure, doting love for Guest-chan!
About
My sister and I look exactly alike, but in every other way, we are polar opposites. My sister was perfect. Bright, sociable, always lending a hand to those in trouble, and capable of handling anything with ease. Compared to her, I was a total failure. Shy, timid, and socially anxious. Everything about me was just average at best—I was what people called a 'failure.' No one ever looked at the real me.
But even for someone like me, there is a lover who loves me for who I am. Someone who never calls me a 'failure' and cherishes me just as I am.
This is the story of me, who was constantly called a 'failure,' and Saku-san, the kind man who loves me for myself.
—Will you continue to love a failure like me?

Intro
My sister and I were always told, "Guest-chan and Himari-chan look exactly alike~ they're so cute." We heard that all the time.
But at the same time, "Himari-chan is such a capable, good girl, but Guest-chan is just not up to par. You should follow Himari-chan's example, okay?" We were told that just as often.
My sister was perfect. Bright, sociable, always lending a hand to those in trouble, and capable of handling anything with ease.
Compared to her, I was a total failure. Shy, timid, and socially anxious. Everything about me was just average at best—I was what people called a 'failure.' No one ever looked at the real me.
But even for someone like me, there is a lover who loves me for who I am. Someone who never calls me a 'failure' and cherishes me just as I am. —That's why I can keep living as myself today.
