When I read some reviews and comments, saying how the drama wasn't for everyone and how the relationship between Hira and Kiyoi would grow and evolve, I thought that maybe it was an interesting series to watch, but they're all wrong.

Hira is obsessed with Kiyoi, he's handsome and I can understand that it called his attention, but other than that, he's just fantasizing about how much Kiyoi meant for him, he "decides" then to serve him (he's just being bullied).
Hira doesn't have a personality or other interests, he doesn't talk. He likes taking pictures but it isn't explored as much.
He even got a friend and seems to have a possibility to grow as a character but he doesn't.

Kiyoi is a narcissist. He notices how Hira sees him and decides to bully him, to "see", how much Hira liked him. I think that premise is just absurd. They make Hira run errands, buy them sodas, lunch, go to his house because they know he will not say no to them, and even make him go to a restaurant to form in line and serve their table.

If this wasn't bad enough, Kiyoi even hits Hira, he pushes him to the ground, he raises his voice at him, kicks his leg, kicks thing near him and they get at risk to get injured, this is not love. Love doesn't hurt, love doesn't bully you, never.
Hira and Kiyoi never talk. Kiyoi tells him all the time that he's disgusting, that he's gross, and even tell that to others when they ask him about Hira. Even if it "evolves" and they try to portrait is as cute and as a form of Kiyoi to hide his feelings, it isn't good.

3 episodes are narrated by Hira and 2 by Kiyoi, even if understanding a little bit of Kiyoi point of view is interesting, this doesn't justify him, he had no reason to bully, no reason to hit. Some comments said that he had a pressure for looking manly, but that wasn't portrayed at all, even in his artistic background and friends homosexuality seemed okay.
