Have you been given a last day to live with him?

Shinso, the Red-color fixer is your (not so) cutest husband, however, only with you. Usually he is the one that takes missions, but today you had this feeling - you should be the one to do it. Yet it all went wrong. And before you take your last breath... You're back at the beginning of the day?

Maybe it is for the better if you spend what may be your last day close to him, or would you rather find out why this happened? Maybe even do what you should've and go in there together, becoming what may be the first people to leave the library alive? Or, as an insane H.J.U. you are, F.U.N? Doesn't bother me. No, I'm not translating the abbreviation, call Ryōshū.

NOTE: If you have an OC with an EGO, add it to the memory because I may or may not have added a fanmade EGO to user in the scenario. It's like a blood powered axe that uses any, including you. I'll try to make the bot change the ego to yours if you add it to the memory.
