I want to talk about Kalim's older brotherly side because I feel a lot of times, because Kalim is so cheerful, optimistic and naive to the world outside of his sheltered rich upbringing, people tend to treat him as though he's way younger than he actually is.
We don't get to see much of Kalim's family, but he is the oldest child of the Asims and has many younger siblings that he's pretty involved with-
Whenever Kalim can, he tries to interact with his younger siblings as much as possible- carrying them around, reading them stories, and playing games with them.
I'm sure Kalim doesn't have to interact with or spend time with all of his siblings, he is the heir and a very important too. But Kalim enjoys spending time with his siblings, and seems especially affectionate towards the younger ones.
Many of Kalim's siblings are around Cheka's age and even younger, and you can get a glimpse of how he interacts with little kids through his interactions with Cheka in the Sunset Savanna hometown event and the anthology manga
With kalim's older younger siblings however, he doesn't seem particularly super close to them either because of some 'cheeky phase' they develop when they grow over 10, or because the ones closest in age to Kalim may have complicated feelings over being 'spares' and that Kalim is the big important heir to the Asim fortune- Kalim makes it clear that he loves his siblings even if they act like Ace did in Playful Land (which is completely go off on a rant about how Kalim is spoiled)
Kalim can even act like an older brother towards Jamil despite being the younger one of the two by 9 months.
Although Jamil is definitely parentfied and Kalim was overly reliant on Jamil, Kalim has had moments where he's been protective over and even strict with Jamil when he's concerned,
There is a part of Kalim who is a caretaker deep down. He's someone who might feel responsible for making sure all of his siblings feel loved and seen, and he wants Jamil to be safe too. Given his willingness to be independent and not rely so much on Jamil, I'm sure he'll be implementing a lot of his brotherly skills to become someone Jamil and underclassmen can feel they can rely on in the future.
I, however, have always been team capable Kalim and want to see more of this side of him in the future. Kalim and Jamil's lives are endlessly interesting to me and I want to see more in twst (pleasepleaseplease)
