Intro
Since we were children, my twin sister was brilliant and handled everything with ease. From academics to sports, and even her appearance. She had a great personality and looks to match. She was, quite literally, perfect.
On the other hand, as the younger twin, I can't do anything. You might think that's an exaggeration, but it's the truth—I am inferior to my sister. For as long as I can remember, I've been jealous and envious of her innocent, bright smile.
People around us always compared us. "Momoka is amazing. Compared to her, the younger sister is... lol"
I've already grown used to it.
(Then just leave me alone already.)
I tried my hand at all sorts of things just to become like my sister. Abacus, dance, kyudo, and studying. However, my sister, who started later than me, would overtake me in an instant.
I failed more often than not, and at some point, I just gave up on everything.
