Part 1: What little info we have of their canon relationship
- Both stella twins originally didn't trust Cielomort. Which is fair honestly, he doesn't make himself seem very non-suspicious. In the first relationship chart, it shows that Louter and his brother are wary of Cielomort, while Cielo being Cielo just wishes to get along with them.
- The two haven't been shown interacting much in main canon, but their few interactions do seem fairly positive.
- The January 2026 relationship chart, like the October 2025 one, does not have any direct lines between Cielomort and Louterstella, however it does show Louter requesting that Cielomort, who probably knows important information the others don't, not be blamed for what's happening. So presumably he probably trusts and/or cares for Cielomort by this point?
- In one 4koma featuring the two and Myunna, Cielomort suggests the possibility Klark may someday move on from being so attached to Louter, which... obviously makes Louter mad. Cielo and Myunna both seem frightened of Louter when he's mad. I didn't have a point to writing this part, I just wanted to include every official interaction I could remember lol.
Part 2: The potential
- In their own ways, they are both caring people, but they're different in how they show it. Louter is gentle and kind, but protective, overprotective even. Cielomort has been known to express concern for others, but he also seems to have a misguided sense of what's best for everyone.
- Cielomort knows things everyone else doesn't. Louter seems to be some sort of prophet. They both know things the average person wouldn't, one is just more willing to share his knowledge than the other.
- Borderline enemies to lovers arc potential since Louter was untrusting of Cielo at first and didn't seem to like him much.
Part 3: How they are to my insane little cielouterpilled brain
- In my head they are t4t. They are simultaneously hetgem, yaoi, and yuri. Just bear with me.
- Louter is just as protective of Cielomort as he is of Klarkstella. He doesn't know what he'd do if he lost Cielomort. Cielo is similarly protective of Louter, but he thinks Louter can fend for himself just fine.
- They are totally that one overly romantic couple that holds hands in public and talk about each other all the time. Their friends have mixed reactions as to whether it's sweet or annoying.
- They are both equally willing to die for the other, if it came down to it.
- Cielomort isn't always completely truthful with Louter. But he tells him plenty more than he tells everyone else.
- Klarkstella didn't approve of them being together at first. He doesn't fully trust Cielomort. He thinks Louter can do better. But, well, as long as Louter is happy.
- Cielomort visits Louter in Little Twin Stars Kingdom every other day, but Louter has only visited Cielomort in Cinnamoroll kingdom a handful of times. He rarely leaves his lords and his brother alone, after all.
- Cielomort gives Louter gifts frequently, though it's usually just small things, like flowers and konpeito. Louter more often does things for Cielo, like cooking for him, or helping to fix any clothes he's damaged.
- Louter writes poems about Cielomort, and about their relationship. Not all of them does he show to anyone.
- "Louter is the very picture of kindness and grace. He's like an angel, and I have no clue what I did to deserve such a lovely partner."
