>>63676616I fucked up the title, it's The Broken Heartlock. Marine pushes for an open relationship against your wishes and it more or less kills (You) inside, and you turn to drinking and meet Lui in a bar. It was supposed to end up with Marine getting cucked hardcore as you begin to fall in love with Lui without actually getting anything herself. It's only got two chapters and both of them contain a decent amount of insanely fury building shit from Marine's end and Anon suffering because of how little he wants to go through with it, but he loves her and she won't stop.
