has anyone else noticed there has been like a decrease of good stories? likeee 2020-2021 w...

You literally spoke my mind I was also going to say this! Too much repetitive grape, abuse, manipulative and incest stuff in bls and straight one's are just porn or they never make mc with a thinking brain. No storyline no plot whatsoever... If you want good stories then I suggest reading the one's with action,comedy,horror themes and avoid the one's with drama, tragedy tags they get boring really fast..

yessss I feel this same way.. I can't tell if it's just me aging, or having read a lot more manga/hwa so everything seems more repetitive. Or there really is a creative drought.
If you haven't already read these, some of my favorites are:
happy of the end (ongoing but i read the raws and trust its peak), all about lust, sleeping dead, escape journey, call, let's go karaoke (and its continuation), happy birthday chitose kun (my own passion project translation LOL), yoru to asa no uta (and its continuation), the man on the other side, bongchon bride, sonokoi jihanki de kaemasuka

yeh I think its also cuz most authors nowadays just follow the “trend” with mostly cold/nonchalant/abusive ml and then weak stupid mc like bruh, and some readers don’t really care about plot and just continue to read those shtty stories anyway just cuz the charas are good looking
