I can confidently say everything you say about you versus MK in this situation, you'd have to apply to her.

Those feelings were going to exist regardless of you. There was ALWAYS going to be a divide in my heart and it's not exactly easy to let go of feelings for someone who has part of my soul in them so even if MK got me to himself first, that was going to be a thing to deal with. No if, only when.

If you think tormenting yourself is a reasonable thing to do, you have to think Mei should do the same if she returns those feelings.

So, can you think someone should treat themselves like you treat yourself?
