I don't know...
But its change.. like how people change during their lives.
Hori changed. She was always putting others expectations and her family ahead of her..but now she can become more selfish and wilful? But yeah.. sometimes her scenes seem awful because rather than jealousy they seem..like exaggerated. But..its still okay.
Miyamura never actually liked his self. It was more of an impulsive decision rather than rebellion, I think when he first got tattoos and piercings.He hides his tattoos and piercings and himself. But now he's more open and frank. Its like having a new haircut is like a fresh start.
That's what I think though.. feel free to think otherwise (=・ω・=)
I think the hori now, is the one she's always been. But never felt comfortable to show it because of the expectations ppl put on her. Think about how the Prez isn't surprised at all by her behavior because that's how she's always been, but I fell like something happened during middle school that made her start putting on the facade? It could have been the birth of her lil brother? & the fact that she has to be responsible for him since her mom & dad work so freaking much.

I used to love this manga at the beginning. She wasn’t as annoying as other girls in other romance manga or anime and he was cute and a good person I just loved their personalities but what happened? Hori was supposed to be a house maid to take care of her brother but now she’s just a tsundere that wants everything to go her way. She just annoys me now. You seriously have to admit that She wasn’t a tsundere but now she kinda is. Also he should’ve never cut his hair no matter what others said. Isn’t this a manga about self acceptance? It just got ruined idk what happened. But the beginning was one of the best mangas I had ever read
