With a 95% chance Yuuji still has feelings for her even if the seasons itself does not say it, they are a couple to look forward to with evidence to prove it during their outing together, though he bears no ill intention towards Shouko, but due to her unyielding obsession with marrying him since their childhood days, he sees her as having a few loose screws in her mind, and fears to even think of his future if he does marry her. It is implied that he has feelings for Shouko, although he denies it.
It is also implied that he is scared from some occasions that is connected to marriage (an example is the ticket to the Kisaragi Grand Park which features a mock-wedding event). In the anime, its suggested that they act like a married couple, though she tends to treat him as a slave.
He is often shocked by a stun gun by her in some situations such as not allowing him to escape on their date, when she has suspicions that Yuuji likes some other girl besides her, etc. From episode 4 and onwards, she is often seen jabbing her fingers in Yuuji's eyes in order to prevent him from looking at the other girls.
Yuuji is close to Akihisa to the point where they can actually communicate without any words. A gag in the series is that Yuuji will attempt to decipher a complicated expression on Akihisa's face and comment on a series of events that must have taken place (that somehow resemble a scene in yaoi stories. While he meant it as a joke, he is always spot-on when this happens. He is the only one capable of tricking Akihisa many times. Their close relationship is often questioned by the girls which Shouko even suspects that Yuuji is having "affair" with him, for comedic effect.
Yuuji and Akihisa didn't get along when they first met, with Yuuji misunderstanding Akihisa as a pervert at the time of the entrance ceremony. However, after working together for the first time, they found it easier to clear their differences.
Yuuji sees Akihisa as and idiot who "has that one thing he has been wishing for himself for a long time". While he is calm and cool and mostly thinks before acting, Akihisa often acts on impulse and guided by his feelings. This leds Yuuji to get irritated with himself, since it's stated that he hates that part of him that makes him remember how in his childhood he hesitated before standing up for Kirishima to the bullies.
Being partners in crime, they can make their way out of Ironman's fists when they aren't thinking of betraying each other. Their close bond is also shown as how fast they can change from arguing to working with each other to achieve a common goal.》
