Add these to your reading list
Grand Blue(this should be the first one you read)
To You, The Immortal(should be the 2nd one you read)
The Promised Neverland
Onanie Master Kurosawa(
Trust me on this its going to be a bit werid at the start but its a sleeper)
Chi no Wadachi
Happiness (OSHIMI Shuzo)
Hi Score Girl
Komi-san wa Komyushou Desu.
Jagaaaaaan(promising new manga)
Gleipnir
mousou telepathy (it may have a lot of chapters but they are all just one page)
Tomo-chan wa Onnanoko!(it may have a lot of chapters but they are all just one page)
Besides the last two everything is short at max they all have 5-36 chapters shortest being Chi no wadachi since it just started a few months back with 5 chapters
Everything i listed could become an anime if there was more chapters besides Grand blue because the writer is against that but i tell you why after you catch up on that.
as an added bonus if you have not read The Breaker then after you finish the Breaker read New waves the 2nd half of Breaker. The breaker and New waves are 200+ so that will take you some time to finish
