TBH, I kinda find Hinaki to be quite annoying? Like, Shunsuke is free to fall in love with whoever he wants, you know. You can't just force him not to get into any relationship just because he's your childhood friend and you want that to remain as such. That kinda seems childish to me. But then, I guess love can make that to you. Though, I honestly would like to know more about Koiwai-san. I'm pretty sure she has some backstory, and that piques my interest.
