not just you. Sometimes it feels like it's because the story was so good and it's all done and I'm sad I can't experience it for the first time again but sometimes I think it's just because I'm thrown back into reality after being so immersed in a story and I feel really lonely when the distraction ends.
I've definitely felt that way a few times, or like I don't want to read anything after for a while because I feel like I'll just be comparing it and it won't be as good/will just disappoint me. Especially when it's like amazing writing vs those clearly mass produced yaois with oversimplified plots and classic cliches just made to make a quick buck, I'm especially afraid of having that experience lol. I have to read some somewhat decent things for a bit and then I'm like okay I don't mind reading the mass produced shit again.
sometimes something is recommended to me so much by people I know have good recs (im on here too much) and i can't bring myself to read it cause I fear I won't appreciate it enough and I'll regret when I finish it. I sat on haruka tooki ie for like 6 months waiting until I knew I could fully immerse myself in it and finishing that HURT SO GOOD (highly recommend btw) I'm sitting on a few rn scared that if I read it now I'll finish it and wish I read it for the first time when I was able to focus fully.

But every time I finished reading a manhwa/hua and manga, I feel empty or hollow on my stomach. I dont know if Im just sad or happy that I finished it especially if the story is so good.
