Isn't this just the softtest. Kenma is really thoughtful. From the very first time they met Kenma have been already observing Kuroo intently. And later on using those observations to deepen their relationship making them understand each other so well.

The fact that Kuroo instantly knew he's in trouble after realizing what he just did and Kenma being obviously unimpress by it by staring daggers at Kuroo gives me jealous Kenma vibes.

KuroKen with their kid. ?

The significance of #13 to Oikawa Tooru. His first appearance was in chapter 13. Then on his first practice match against Karasuno he wore a #13 jersey. And now his ARG jersey is #13 which was José Blanco's jersey number, his inspiration who roused him to become a setter.

Everybody gangsta until we see this Kenma on the Nationals playing against Karasuno finally animated.
