It's pissing me off how he knows he's a slave who can't decide what happens to him but he still keeps turning away his every chance of escaping because of his feelings.
He can feel bad about himself AFTER running away from moLister. Right now he's in the most vulnerable position, how is he expecting to run away from this marriage?
He knows Lister won't just accept his rejection and walk away? when did he ever? He knows he's a irredeemable monster but he's still severing every connection he has to people who are his only way of escape from this situation
He can escape with ML, use him in politics to get out of the marriage, or just trying everything in his power to put a stop to this marriage instead of sitting on his ass and watching the days pass.
Is he expecting the solution to fall out of the sky? because Lister isn't a person who listens to what MC wants.

MC is pissing me off so much like?? the whole point of being a slave is that you can't have human rights and you can't decide what happens to you? What makes you think that a horrible nasty bastard like Lister is gonna listen and let you be?
Like?? he has to know right? he's a very smart person but for some reason when it comes to actually make a decision he always makes the wrong ones for no reason.
''I won't marry Lister, I'll rather stay as a slave'' well guess what sweetie? being a slave means you don't get to decide if you'll marry him or not... Because you're a slave...
Once the queen is gone, there's literally not a single person who can stop Lister from doing whatever he wants to you, be it rape, forced marriage or confinement in a tower.
Why would you turn away your only escape option from that inevitable future?
Because again, HE'S A SLAVE!!! he can't run, he can't escape, he can't ask for help and he keeps ignoring HIS people who are trying to help him??? What?? I thought he was supposed to be a smart chaarcter?.
Honestly the ML needs to stop trying to look all cool and nonchalant and instead just fucking tell the truth for once. Your aurafarming attempts are pathetic man, just talk to him normally dork.
