I read a fate dj a while back on a certain site, when I went back to check today, it was gone. It was Lancer x Archer and a R18 story where they are both office workers. Lancer is an overworked employee who transferred to Archer’s office. Archer worries for Lancer, brings him bento, and they eventually become FWB. Does anyone know the title?

Pretty sure it's 24jikan kurasemasu ka/Can you fight for 24 hours by Ubiquitous

Yes, I realized that now! It was under a different tag on the website…I’m stupid. Nevertheless, thank you!
