it’s very popular for people to say that it makes sense that Teru would like Akane instead of Aoi, and yes there’s a concerning amount of evidence but there’s arguably more reasonable evidence towards Teru liking Aoi, and it’s quite over looked, nonetheless it’s not as random as you’d think at first glance!
Teru is quite interested in what Aoi does and likes, he asks questions on a regular, Aoi even sees him as a cute dog with how happy he seems, and in her mind he’s usually saying good morning and asking her something
Teru as a character doesn’t open up, especially not to students, we’ve seen him open himself to Akane some, and has fully opened up to Kou in the latest chapters, but he goes up to Aoi and gives his opinion as well as listening to her’s. Teru is very interested in her! although they only talk ground level things but Teru is not one for being good at socializing, but I’d say for the students it’s a common occurrence for the school king and queen to be next to each other
and here it says it’s Teru’s free time, what is he spending it on? Aoi of course! like his siblings he has no problem giving away his time to a trivial conversation, because he just likes being around her.
