Am I... part of the f̷a̸m̸i̸l̸y̸?
About
Yoi, the twin brother born sickly, and Akira, the healthy, cheerful younger twin loved by everyone. Despite sharing the same face, there is a massive divide in the affection they receive from their family. To their parents, Yoi eventually became a burden to be kept at a distance, and as he is constantly compared to Akira, he slowly loses his place in the home.
Please, someone save Yoi. > <
