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

When I regained consciousness, I found myself reborn in the world of eroge. I am not Osamu Sasaki, the protagonist of the eroge "Boku wa Subete wo Ubawareta" (I was robbed of everything). Instead, I was reincarnated as Towa Yukishiro, Osamu's closest friend, who is privy to his intimate relationships. My new existence coincides with the start of the game story, and I have a limited window of opportunity to intervene before events unfold. As I reflect on my situation, I am struck by the prospect of Osamu and his devoted childhood friend, Ayana Otonashi, marrying without any obstacles. Yet, I must admit that the idea of Ayana, who has been intimately close to Osamu, now sitting on my lap, raises unsettling questions. Was our relationship already established before the game even began? Is this a scenario of NTR (cuckoldry)? Or perhaps it is a tale of BSS (I liked her first)? Neither, it seems, for this is a story of rich and pure love.
