I love the idea of Kuroo going pro and Kenma attending all his matches and bragging about him all the time on stream and telling everyone to support him. Kuroo being the Kodzuken merch model and doing videos with him.
Kenma's fans thirsting after Kuroo and Kenma getting all possessive and being very passive aggressive about it "if only he wasn't taken and very in love with his boyfriend."
Kuroo wearing their engagement ring around his neck during matches and kissing it before the start of the match.
Kenma wanting to sponsor Kuroo and Kuroo refusing adamantly because "you're a nightmare boss. no thanks."
"But I already sponsor Shoyou and he's absolutely fine."
"Darling, you threaten him every time he comes over to visit."
"No I don't."
"Babe, he's scared shitless of you."

Kuroo waking up in ungodly hours to go for a jog but Kenma doesn't mind waking up for the bit where he does his morning yoga. Smirking in bed as Kuroo folds his body back and places his feet on top of his head very casually. wolf-whistling when he bends down to touch his toes.
Kuroo forcing Kenma to eat healthy nutritious food and go with him to the gym at least twice a week. Which despite being very difficult and painful, Kenma doesn't hate when he actually starts to gain some muscle and become stronger, Kuroo treating him with a kiss after every set.
Japan qualifying for the Olympics and Nekoma is all there to support their former captain, screaming as Bokuto slams the ball across the net and Kuroo runs into his arms, crying in joy.
Kuroken getting married and Kuroo retiring to become a coach as one of the most respected volleyball players of his time and a technique master especially in read blocking. Always bringing up Nekomata and how much of an influence he had on him.
