Emi's manga / #Horror(2)

I am a simple lad who loves to reread manhwas I've loved however.... I wouldn't be able to reread this. It made me cried and not because it was so good but because many characters that didn't even matter or were revenant to the story. We didn't get any backstory for school, while its a interesting story at heart, its not the best for those who reel in to details. It left me empty which and my god the grape scene in the cave??? The ml was on some bullshit, mc and hana were probably the only characters that I could feel bad for.
