Day 21: A pairing you like and no one else understands why.
Does Lockon x Haro [Gundam 00] or Setsuna x Exia [Gundam 00] count? lol. I honestly like Lockon (Neil) with Haro more than anyone else he's paired up with. Same with Setsuna, he's such a Gundam baka that I like him with Exia more than anyone else lol.
Day 22: A pairing you hate and no one understands why.
I don't think there's a pairing that nobody else hates except me lol. But I quite dislike Phoenix x Edgeworth [Ace Attorney], even though it's like the most popular pairing of the fandom >__>
Day 23: A crazy love triangle/quadrilateral that worked out great.
Lol do love triangles/quadrilaterals ever work out great? Unless there's a harem ending, someone in the triangle/quadrilateral would end up getting hurt. I don't know if Kira/Lacus/Athrun/Cagalli [Gundam SEED] counts as a love quadrilateral, but it worked out great. It started off as Athrun/Lacus, and it almost seemed to be Kira/Cagalli, until they revealed the twins thing and ended up with Athrun/Cagalli and Kira/Lacus, which worked out great.
There's also Kyou/Tohru/Yuki [Fruits Basket] that worked out pretty well. Yuki realized he saw Tohru as a mother figure, and let Kyou (who needs her more) have her, and found someone else.
Day 24: A crazy love triangle/quadrilateral that worked out badly.
Most love triangles? Actually a lot of love triangles just don't really resolve. I don't know if it ended up badly due to the love triangle, but the Mwu/Murrue/Natarle dynamic sort of has a tragic ending. I don't even know if it counts as a triangle, because Mwu and Murrue only have eyes for each other, while Natarle... I think she has a slight crush on Mwu, and cares about Murrue in her own way (I don't really see it as romantic or sexual love though). But being Natarle, she doesn't do anything with her feelings (if there even is any to begin with, I might just be reading too much into it lol). Whatever their relationship, I love their dynamic. Unfortunately it ends with only Murrue surviving the ordeal (at least in the original SEED ending). I don't know if it counts as a triangle that ends badly, more like tragic and dramatic, but it's the only triangle I really care about lol.
There's also Neo/Murrue/Andy in Destiny, but I don't think it worked out badly. While Andy did end up all alone in the end, I think he is able to just move on.
Day 25: A pairing that was/would-be adorable, but could never work out.
Setsuna x Feldt [Gundam 00]. They're about the same age, and both has a connection to Lockon. Feldt gave Setsuna the flower in glass case, asking him to come back, and she was frantically searching for him at the end. They're kind of adorable together. But really, they're more like brother/sister I think. Feldt sees Celestial Being as her family, and Setsuna... has the romantic awareness of a brick no romantic inclination whatsoever lol. But to be serious, I don't think Setsuna sees Feldt as a potential partner.
Day 26: A pairing that you hated and ended up loving.
I don't think there is any. I guess the closest would be Shinn x Luna [Gundam SEED Destiny]. I used to hate the pairing, because of how unrealistic it is, and how fast they just got together. While I still don't love the pairing now, I don't hate them as much anymore, after rewatching Destiny. Luna is a better fit for Shinn than Stella (who's unstable), and while they got together due to grief and kind of rebounding, they were friends before I guess.
Day 27: A pairing that you loved and ended up hating.
Kira x Lacus [Gundam SEED]. While I don't really hate them, I just don't love them anymore. They used to be my second fave ship in Gundam SEED, and I thought they were cute together. But then Destiny happened, and then they became boring and I stopped liking them.
Day 28: A pairing that you will never understand.
Most fanon pairings that have no canon basis, like pairings between characters that don't interact, hardly interact, or only interact with hate. If I had to pick one, probably Sesshoumaru x Kagome [Inuyasha]. They barely interact with each other, yet this is like one of the most popular pairings for the series. I guess I don't really hate the pairing, I just don't understand how they can be a pairing in the first place =\
Day 29: What ship had the bed proposal?
Uh... no ship I know of lol
Day 30: Your favorite pairing forever and ever and ever!
OTP forever =D
