Ore no Osananajimi ga Ero Haishin o Shiteita Ken ~Jimi na Kanojo no Ura no Kao wa EroEro na Haishinsha Deshita~

In a word, normal. The main character, Taichi, who leads such a peaceful school life, has one thing to look forward to that adds color to his daily life. It is the live streaming of a certain streamer. Taichi looks forward to her cheerful, joyful, and slightly naughty live-streaming of video games. Then one day. One day, while he was watching her live streaming as usual, he felt a small sense of discomfort. "Could it be that this girl is......?" I didn't know anything about her, but I was shocked to see the backstage face of my childhood friend. And that was the beginning of everything. [Translated from Getchu]
