“Something about changing and getting so happy is scary,” Hikari tells Itou. So much so it makes him overly self-conscious and embarrassed about how intensely his heart beats whenever Iroha is near. Unfortunately Hikari still has much to learn about communicating his feelings good or bad, so he ends up ignoring Iroha and even pushing her hand away.
The only answers he can give her are “sorry” and “it’s nothing”, as if she wouldn’t understand. He’s still too stuck inside himself to trust someone else, especially with emotions he’s never had and can’t begin to explain. So it causes a rift.
Almost simultaneously, a girl slips on a banana peel and Hikari helps her up. It’s his classmate Ishino Arisa, whose first instinct upon realizing who helped her is to call him “gross” like all the others do. But later, she doesn’t run away or dismiss him when he tries to seek advice from someone who doesn’t make his heart pound.
Because Ishino also likes someone, their common ground on which to lay the foundation for a conversation. Part of her is worried this gloomy dude will commit suicide if she leaves him alone, but part is just as receptive to talking about the strange feelings people get for one another, and because neither of them share those feelings for each other, there’s no pressure.
Ishino decides a good step to take is for Hikari to lose the bangs as part of a larger effort to look more presentable (and less gloomy), but she can’t take a single snip of hair (with craft scissors) when Iroha arrives and declares that Hikari “belongs to her.”
Hikari thought she hated him for how he snubbed her, but her rudeness with Ishino is ample proof that’s not the case. Nor does Hikari hate her; they’re merely misunderstanding each others’ discomfort with the new and complicated emotions they’re feeling, as just about anything new makes people uncomfortable.
Speaking of comfort, on both the advice of his mom and the fact Iroha likes the same show, Hikari gets into baking as a means of both expressing his affection for Iroha and releasing pent-up stress (with which, as we all know, eating sweets can help).
Iroha is contrite towards Ishino and before long, Hikari is one of a circle of four. Iroha may claim to “not need” friends, but what else do you call four kids at school sharing each others company (and cookies) and talking to one another about themselves?
When asked, Ishino mentions things are going okay with her boy Shun, but the others soon learn he finds Ishino “convenient” in the way she lends him money and doesn’t mind the sight of other girls’ clothes in his room. He’s a cad, but Iroha doesn’t feel its quite their place to intervene, and Hikari and Itou aren’t about to disagree.
However, Iroha breaks her own rules and pummels Shun with her bookbag, not necessarily to defend a friend (she’d still say Ishino wasn’t one), but because he was pissing her off by calling Ishino stupid within earshot of Ishino. Ultimately Ishino decides to break up with Shun, but her stoic face is quickly soaked in tears; she’s not happy about it, even though she thinks it was the right thing to do.
To help dry his new friend’s tears and reduce her stress levels, Hikari suggests they head to the roof and eat the cheesecake and donuts he made. When Iroha gets some chocolate on her face he wipes it off with his hand, and Ishino declares that while she wan’t jealous of them before, she is now.
Hikari marvels at how there are only honest girls around him, but he doesn’t know how lucky he is. It’s up to him to be just as honest with them, as well as Itou. I’m not saying fake or deceptive people are lame, but I don’t think Hikari is compatible with them at all. He’s someone who needs things said to him straight, and hopefully he’ll pick up the habit.
And so, up there on the roof, trying not to worry too much about what the future might bring, Hikari is simply happy he can be a “normie”, and interact with these very exotic creatures called 3D human friends. It might feel weird, but he’ll surely get used to it.
