i have a sashisu fic idea. it's a combination of ghibli vibe and a japanese countryside instead of a busy citu. so here's a short summary, but the fic will only be published in AO3:
Shoko appears like a boy because of her short hair. Other people often tease her about it. Suguru comes from a family with strict rules. He is very focused on his studies and tends to be serious and stiff. Satoru, on the other hand, is carefree and brings them all together. However, little do they know, one of them is going to meet a tragic fate.
