Besides, will Eren and Mikasa end up together?
Except for once (last episode of season 2 and chapter 50), Mikasa was weak. Then I'm sure in that world, Eren will finally realize Mikasa's feelings. And they will surely end up together. Even at the current point in the manga, Eren has grown up so much.
Beside above, does Eren kiss Mikasa? The answer lies in the fact, that they looked like they were going to kiss. They weren't, actually, it was just Mikasa :D. Spoiler alert: Eren hasn't been shown to reciprocate Mikasa's feelings of love, even till now in the manga (Chapter 95).
Beside above, does Eren care about Mikasa?
YES. Of course he do, she is like a sister to him! well if you guys read the manga instead of watching the anime since WIT keeps pushing eremika for some reason, eren has always resented mikasa. Like, there is always a character in an anime/manga that goes through a phase where they push away the ones they love.
Why is Mikasa so obsessed with Eren?
Mikasa is attached to Eren because he gave her a second chance in life when she was doomed to die. Eren gave her everything. And then it was all taken from her again. Her world was shattered when her parents were murdered.
