what's worse of all is that each character had acted differently almost constantly, it was all over the place.
anyway, from what i remember i liked these and most of them are short, nearly all are romcoms
Rental Girlfriend Tsukita-san (rent a girlfriend but made by a more competent mangaka)
Chicchai Senpai ga Kawaisugiru (smol coworker senpai, it has two short sequels)
I Sold my Life for 10000 yen per Year (tragic ending but it's amazing)
Kukakura-san to boku (i guess it's similar to Kubo-san won't let me invisible)
Nega-kun and Posi-chan (somewhat lacking in regards of romance but the first two volumes were great)
Kimi to Picopico (longer but I liked the interaction between both leads a lot, also what's not to love about a gamer gyaru!)
Do Chokkyuu Kareshi x Kanojo (
YOU WILL READ THE ENTIRE MANGA AS IF THEY WERE SHOUTING)
