Wtf is that mission and how tf is that more important than treating her like a person? And for all 5 lives at that? You just decided now to end the freaking mission for what? Because she doesnt want you anymore? You cant justify yourself at this point no matter what, so just stop and let her be with the devil instead. The devil was the lesser evil in this story. My prince.. you deserve to be unloved. It hurts in 4D when you said you were aware of the regression all this time.. but made her suffer nonetheless and killing her at the end. No matter what tf that mission is.. fvck off i beg you. You are handsome, you are rich, you are powerful and now you look so sad and exhausted too.. and you seem to genuinely love and regret doing all those things.. you must have gone mad from suffering after every life.. but no. Had you truly loved her.. and cherished her.. you'd have fvcked that mission the first time and maybe do something to avoid such tragedy.. so no. Just no, non, noh.
