@Zenbonzakura: don't turn away from it. from the beginning till now, knight always receive fooly help. so it's now her turn to help him. If not, the author wouldn't need to add that flashback
@regalia001 | Nah, pretty sure he's already dead in the Demon Leo's world
"How did he die?" is probably due to an accident/incident that happened either because she rejected him or because it was too late to make a confession. Suicide is also a probability.
[For clarification mods/admins, this is just heavy speculation that resulted in a lot of hypotheses (plural), I don't have the ability to see into the future]
Merry late Christmas for everyone who's reading this
Despite how much the manga implies Fooly will die, I believe it’s just not gonna happen. I’m betting at the last second he gets saved (probs the life force of the defeated demon lord or whatever)
