I've been in love with him around 2012/2013, so he's very meaningful to me & I can be possessive.
If I was stuck in Sword Art Online, I would either be too afraid to fight incase I would die or I be curious and excited to explore the world knowing the risk of death. I believe I would pass by during a small interaction that would include Klein approaching me to flirt with or offer help seeing me alone. Even if I said no to his advances at first, Klein is respectful and keeps his hands to himself. (He's never touched another girl without permission.)
Either way I would end up being Klein's friend regardless what option because he wouldn't want a girl to be alone, because that's just how he seems to be.From Sword Art Online

Headcanons:
-Klein is a Deredere.
-Easily flustered/blushes from receiving affection
-A cinnamon roll, but would fight for his friends/lover <3
-An emotional baby that isn't ashamed for crying
-Type of guy who does anything for a girl
-Struggles with nightmares/trauma after leaving SAO
-His love language which is acts of services, and words of affirmation
-He sometimes whines when he doesn't get attention <3
-Klein is a switch. Often being the bottom/submissive.
For me personally I want him as the top.

Main/Husband of 12 years & 9 months
I really love Klein since I was 10. He's been my hubby for 12 years. 💖
He often tries to act cool and be a 'ladies' man, but he often fails. His actual self is friendly, kind, caring, adorable, cute, romantic, loyal, supportive, and attentive to his friends. Obviously attractive of course.
I also really love that he's also very attentive and caring. Klein was shown to be concerned about Leafa (Suguha)'s struggles with being underwater and pointed out to Kirito, that Kirito should help her.He can be very reckless jumping headfirst into fights to defend his friends as shown multiple times.He often cries in front of others (usually about his friends). He doesn't seem or feel embarrassed for crying in front of others which I love. I love that he breaks the toxic masculinity stereotype so much! He's the most perfect man! I absoutely love him so, so much!I could write a whole essay why I love my husband so much. I can't remember how or why I fell in love with Klein, but it was definitely because his character design, and personality! He's such a sweetie, and such a huge SIMP who adores and cares about his woman!

Champion Leon, he was my second crush on a character after a long time not having one.
2023 I started to watch Pokemon Journeys for the first time, he ended up appealing to me more for his personality and maybe his design grew on me over time. Eventually he ended up sticking around. I love quirks, his odd outfit that people trash on, and his long hair is beautiful too.

Headcanons:
-Has ADHD
-Insecure about needing to be perfect all the time and fearful of people thinking he's not this great celebrity everyone look up to
-Leon is a switch. Often being the bottom/submissive.
For me personally I want him as the top.

1 year & 8 months
To put him simply, Leon comes off as arrogant and an egotistical trainer due to him having the tendency to flaunt himself as the #1 Champion of Pokemon battles, but in the anime for certain moments he's acts like a normal person and have vulnerabilities. He's not perfect and that's okay. His insecurities are valid as anyone's.
He's a very sweet and caring man who's just like any regular person. I love that he tends to get lost which is an odd thing, but I appreciate him regardless. I love he's imperfect. I think Leon being too perfect at everything would be obnoxious.

I originally didn't not plan to fall in love with him, but I ended up pulling Gallagher while trying to get Archeron. I quickly fell in love with him after learning his lore/story!From Honkai: Star Rail

Headcanons:
-Has Depression
-Dog behaviors
-Often fidgets with his lighter
-Messy/Unorganized

1 year & 4 months
He's very humorous, a gentleman, courteous, somewhat depressed (hinted in his lore), stern, polite, unorganized, slovenly, and indolent. He seems to no longer take pleasure in apprehending or catching suspects anymore, seeing no accomplishment in Gallagher’s eyes and is rather described as profound emptiness and melancholy. (He's so depressing, I really want to help him and love him so much.)
In-game his voice lines/dialogues shows he has humor, jokes about his dog-like nature that he used to be a little terror, biting everyone in sight and growling noises. He dislikes chocolate, and the bottom of his shoes has paw prints. (I love the fact he hates bread just like me)More about Gallagher because he's a very in-depth and complicated person:

Just like Gallagher, I originally didn't not plan to fall in love with him. It happened when I was trying to pull for Ellen Joe, and got AntonI ended up loving Anton for his personality. He's so caring which I love so much in a guy. Anton while is masculine, I like that he's written to ignore toxic masculinity as his entire character while still having the healthy stereotypical buff guy who loves to work out trope, etcFrom Zenless Zone Zero

Headcanons:
-He is socially inept
-Anton is a Deredere.
-Easily flustered/blushes from receiving affection
-Looks like he could kill, but he's a cinnamon roll and a wholesome bean <3
-Kind of messy, but still organized. Will be slightly irritated if something is out of place.

1 year & 1 month
He's hot headed, loud, cocky, overly confident (shown multiple times in-game he's rushed into fights without thinking), cheerful, helpful, and brash, and despite his appearance he has a good heart! He often doesn't like sitting around doing nothing. He can be impatient usually always excited and ready to do something!
In a few artworks its shown he enjoys eating, getting excited over food, and spending time with friends!It's implied he's a very loyal person in the game,'He'll have your back no matter what, even if the protagonist takes a dark path.'He can be very caring and concerned for others: Anton had set up demanding tasks for the construction workers, hoping to push them to their limits and unlock their true potential. However, witnessing their struggles and diminishing confidence, he couldn't bear to see them suffer any longer, so he secretly completed all the tasks in the dead of night.
