No I get that but I think the author kinda wanted Hanzawa to be that straight person who comes around to the idea of gay relationships and thats his whole arc, so (though I myself do ship tashiro x hanzawa :P) I think he was intended to be straight and have no real love interest BUT THEY HAVE SO MUCH POTENTIAL
I think that role is better suited for Ogasawara or Shirahama, as for Hanazawa ending up with Tashiro would be an interesting storyline, because when his brothers said they liked guys, their mom asked him and she was happy when he said he likes girls. I think at the time he was still verry young and might've not known who he likes, so him later finding out he likes Tashiro, while not knowing what to do with these feelings would be worth reading

.........they're cute and everything, it's also nice to see that their relationship developes nicely, BUT it's so evil to mention Hanazawa so offen and then not give a Tashiro x Hanazawa moment at the school festival. Come on we have Sasaki to Miyano, Hirano to Kagiura, but I need more like Tashiro x Hanazawa or Ogasawara x Hanazawa (the older brothers)
