This episode is bookended by instances of Takagi making physical contact with Nishikata and Nishikata having to deal with it. He seems to be mostly fine with her holding onto him while they bike, but it was a long, tough road, and his ribs are ticklish.
Now that they’ve mastered the skill, Takagi says they won’t have to practice anymore, and gets Nishikata to say he’s both relieved and bummed out (though in truth its probably mostly the latter).
The second term starts in a typhoon, and Nishikata stands in the wind and spouts giddy shonen lines like a chuuni. Naturally Takagi spots him doing this, and gives him a chance to win her silence. He fails, yet again because he dismissed his first, correct guess as to why she didn’t have her bike.
The marathon segment is an apparent test of wills, as the two have stakes on winning – having to do what the other says, as usual. When Nishikata’s classmates ask if he’s going out with Takagi, his reaction is Pure Girl-from-100%UL.
He’s also been training extensively in order to be good at long distance, and initially employs a “mind emptying” running mentality, but emptying his mind only makes it easier for him to fill that space up with Takagi.
He gets trapped in a mind game in which he tries to run far enough ahead to spook Takagi, only for her to pull the very same trick on him, only successfully. And again, she gave him an honest chance for him to win (he merely had to touch her) which he simply did not take.
On another trip to/from school, the touching theme continues, with Takagi taking the initiative (of course) by starting a habit of poking Nishikata in the ribs, with the very clear implication that he is welcome to poke her back.
When he doesn’t, she beats him in another match (making a funny face to make him laugh), and rather than forbid him from eating rice or reading 100%UL, she has a simple punishment: all he has to do is poke her ribs.
He gives one half-hearted tap against Takagi’s side after much hemming and hawing, and Takagi reveals that while she’s not ticklish in the ribs, she is ticklish in the armpits. Again, Nishikata is welcome to test her claim, but he’s too embarrassed.
Summer may have given Takagi a few new opportunities to tease Nishikata, but it also brought the two much closer together. We’ll see what the new term will bring.
