I’m wondering if he hid Taehan’s identity to keep him separate from MC. He definitely has a personal interest, but this may be a sexist case of him not wanting Taehan to “drag down” a promising young athlete who will make money and build reputation for the gym. Even though Taehan was a medalist, he’s the mother in this scenario, so he’s “going down with the ship” no matter what. By keeping them separated, he could make sure MC focused on his career rather than supporting a family. MC could go on to make a lot of money, accomplish a lot, and raise the gym/coach’s reputation
Either way, it seems like he capitalized on the amnesia and strain of pregnancy, childbirth, and infant care. His reaction told Taehan what his real priorities were. It’s suspicious that he isn’t excited/happy at all to hear his mempries are coming back, but seems to want to know as much detail as possible. Probably for damage control.

Jupiter seems like just an overconfident asshole with a big ego at first, but the more I learn about him, the more sorry I feel for him. He has been isolated and undersocialized since birth. Guiding is likely the only thing he’s ever been evaluated by and built an identity around.
His callous words and actions are a lot less cruel when viewed through the lens that he has had very little normal interaction with people. Everyone so far has been KOd by his guiding to the point of irrationality, so when Caden rejects his guiding, it feel ps like Jupiter himself is getting rejected.
There is no doubt that his father did not raise him as a proper child, so I wonder how much he may realize as he interacts withCaden.

Just because he managed to manipulate his way into a politically obligatory arranged marriage doesn’t mean she’s going to magically be interested or affectionate towards him

He only has himself to blame as a coward who tried to eliminate any other possible option to make himself the only choice rather than actually trying to build a genuine relationship with
We see Jay’s true motive come to light. He just wanted to rail shin in a police uniform
