With KuroYama comes TsukkiKen. Kuroo and Yams become a thing and Tsukki and Kenma are just kinda there, third and fourth-wheeling to the group couple and they just decide to be their own thing and they're able to keep it on the down low until Kuroo walks in on them cuddling and maybe making out a little and he gets super excited like "I'm with your best friend. You're with my best friend!!1! Double dates!"
