Eroge no Heroine wo Netoru Otoko ni Tensei Shita ga, Ore wa Zettai ni Netoranai

The protagonist wakes up in the world of an eroge, realizing he has not been reborn as the main character, Osamu Sasaki, but as Towa Yukishiro, his best friend. Towa is in a situation where Ayana Otonashi, a heroine devoted to Osamu, is emotionally close to him. A year remains before the game's events begin. The protagonist has no interest in being in a secondary role and is determined to change the situation. When Osamu is absent, Ayana shows unexpected closeness to Towa, raising questions about their relationship prior to the game's start. The story explores whether this is a case of being cuckolded, or if Towa's feelings for Ayana developed earlier. The narrative presents itself as a romantic tale centered on Towa and Ayana.
