Zenin Netorare Ntr Subete Ga Ubawareta Rj0131 -

"NTR" stands for Netorare, which is part of the name. The "Subete Ga Ubawareta" part, which translates to "Everything Was Broken," suggests a narrative where the protagonist's relationships and trust are completely shattered. The "RJ0131" is likely a publication code, common in Japan for manga and doujinshi, so this is probably a specific doujinshi or self-published work with that code.
