First question is, "Why do you like Mikasa so much?"
I met Mikasa on the first night of training to become to a soilder. I went in there not knowing anyone, I had no friends. Then she stood out to me, not just because she looked different. She looked like she knew what she was doing, unlike Eren.
But getting back to your question, Mikasa is extremely beautiful. I haven't met a single person so far to match her beauty. I know nothing will ever happen between us, but that's okay to me. Because I do care about her like I do with the rest of my friends.
Eren needs to stop being so stubborn, he has a beautiful woman such as Mikasa right in front or him. It's obvious she loves him, but he is just completely oblivious. I hope she gets to live happy though, the shit she has been through with Eren. They both deserve it.
