To him, love is less of a romantic matter and something more of comradeship, his life experiences probably shaping his views on this. He mostly sees love as something akin to absolute trust and being able to place his life in the hands of another person.
♠ - What are they afraid of?
The first thing that comes to mind would be dying without at least fulfilling his almost purpose in life. He doesn't want to die a meaningless death. On a more basic note, Levi isn't too fond of fire in general.
♦ - What is one thing about them that they are most proud of?
His skill and prestige in battle. Levi's also rather proud of his ability to at the very least survive and eventually excel at any situation he's placed in.
♣ - What is one thing they find embarrassing? (About them, others, things in general)
Levi dislikes being out with a group, large or small, and being associated with them when they do stupid or careless things in public. He wouldn't show his embarrassment but it's there all the same.
★ - Do they prefer daytime or night time?
Night time so he can actually get some rest without getting bothered. Most of the time, anyways.
☾ - Are they prone to nightmares or a dreamless sleep?
He doesn't have nightmares daily but they are certainly a regular occurrence. Levi can rarely remember what exactly happens in them but they are certainly enough to jolt him awake in the middle of the night with his heart racing.
☼ - Something that/Someone who makes them happy
Being out in nature is usually enough to put him into a relatively good mood but catch him near the ocean or the beach and you might be lucky enough to even see him smile.
☁ - If they're caught out in the rain how do they react?
Disgruntled and grumpy because his clothes are now soaked. He's always loved the smell of the earth after the rain is over but if he can help it, you wont see him outside when it's actually raining.
♪ - Are they musically inclined?
Levi doesn't know how to play an instrument and his shower singing could admittedly be... a bit better. A lot better.
♫ - What kind of music do they enjoy?
Levi prefers classical music because he's a boring shit. One time someone tried to introduce him to rap and it didn't go down well.He claimed they were just playing him a track of turkey calls.
✓ - How do they react to praise?
Levi doesn't particularly enjoy lavish praise and it actually makes him more uncomfortable than anything. However, he doesn't mind modest praise and he'll probably mutter at least a 'Thank You.'
✕ - How do they handle rejection?
Rather well, actually. He knows to just move on with his life and will not dwell on the past.
☺ - Do they prefer sour or sweet treats?
❄ - Favorite season and why?
Definitely fall. Winter is too cold and he dislikes the snow, too much rain in spring, and he would rather get hit by a car than voluntarily step out into the burning hot sun of summer. Also, autumn has always been a beautiful season to him.
☮ - Do they have an idol or someone they look up to?
Not idolize but he's always looked up to Commander Erwin Smith.
❤ - Do they have a love interest?
✖ - Someone they just cannot stand?
♔ - Do they value loyalty?
Loyalty is one of the things he values most.
♕ - Do they trust easily?
