I accidentally closed the tab without realizing it and lost it, but it was a one shot manga with four different stories. First story was this broke college girl named Hiyori(?) and this guy who’d ask her to hang out, but she’s usually busy with work or whatever. They go see some fireworks together. Another story was childhood friends named Makoto and Haruki and she goes to his basketball game. Last story I remember was this girl who draws manga and she’s basically like “I could never be the heroine of a romance manga” and the guy finds her work and offers to help her with a deadline. I know this probably won’t help but I believe the author/artist is ameko. If anyone can please help me find this, I’d really appreciate it!!!

Found it: Shiotaiou no Mobuko-Chan Series
