That's lowkey how this manhwa is
welcome <3 I will say tho, as from what I remember about those mangas, i think only the disability and their partner loving them regardless part is similar to what you described, rest all is specific to jayvik so can't recommend anything exactly like that.
Also you can try this out too, the uke in this has a personality kinda similar to Viktor, i mean he doesn't have a disability but he's extremely intelligent, you might hate the seme tho so warning beforehand but either way if you wanna read something plot specific with an intelligent uke then I'd recommend this -

Please indulge me in some recs for story’s where the the main guys have the same type of relationship like Jayce and Viktor.(if you don’t know who they are, Viktor is a character with a disability. He knows others look down in him, and he knows and accepts how much his disability affects and defines how other think of him, but he’s not like an “oh!~ I’m so weak and feeble, how could anyone like a cripple like me!?”, he has an actually personality, and he’s super smart(probably the smartest in the show), and he’s super cool and beautifully and amazing, though he does hate his body for being how it is. And Jayce is a person who looks up to Viktor and loves him completely. In Jayce’s eyes, Viktor is the most admirable and beautiful person he’s ever met. He doesn’t look down on Viktor at all for his disability, in fact, he says(SPOILERS) “You’ve always wanted to cure what you thought were weaknesses. Your leg. Your disease. But you were never broken, Viktor. There is beauty in imperfections. They made you who you are. An inseparable piece of everything.” He says this before they die together, so if you couldn’t tell, Jayce truly loves Viktor, but Viktor up until the very end never truly understood how Jayce could completely love him for everything he is. Weaknesses, sickness, disability, everything. So yeah.) oh btw, Viktor is more of a cold and un-social person. He’s introverted but not because he’s shy, but because he doesn’t like people.
