And she loves Eren in fact he's the only man in her life to ever bring her some kind of happiness. Even her and her father have a toxic relationship. Yet this cute oblivious boy she met brought her joy and help shift her world view, with his ignorant yet passionate ideals.
His enthusiasm and dedication for getting stronger as well as going against the current ,against all odds had a great impression on annie.
She thought it was especially cute how excited he was when learning a new move, it made her smile
She had wished she could be like him but admits she's a weak person at heart, scared to oppose the marley empire, yet she wishes for the courage to do so.
When she wakes up next chapter, she'll learn that eren possess the founding titan and humanity now has the colossal titan under their control. Meaning opposing marley is now a viable option and not just stupid optimism. She'll then join eren and the walldians to help save the eldians and destroy the marley she hates so much. So that the eldians stuck in marley, weak people forced along the current, can be considered people too.
