Einlion
Well Line is officially lost. And please Ein bully Bell all you want he is a very bully-able character and, since he is not the MC, definitely deserves it. You know a better description of the luck development ability might be that it helps things happen that you want to do, but don't have the guts to do.
Considering that Bell is fated to become a mini zeus, could Vahn not simple ask Bell (with the servering fate dagger in hand) not to inappropriately touch woman who he is not acquainted with and belong to others, otherwise A he will be placed in a box which has a sealed off space for 10 years with food and yaoi mags, or B vahn will stab fate. Considering how fate seems sentient I think it would consider these options.
