A Little Less Conversation | Neil x Protagonist
Based off of the AMAZING fanfic, "Neither Argued Nor Temporized" by Kryptontease on AO3 (https://archiveofourown.org/works/254...)
Well, that's what I was trying to go for anyways. It seems more like "Tenet but Neil and Protagonist also started sleeping together"... oops? ¯\_(ツ)_/¯
