Okay I forgot another one again today. In one of the arcs, MC plays an autistic child whose parents both died in an accident and was later adopted by a family friend. MC's stepbro is the ML. The piano tutor (original FL) is jealous of MC's piano talent and told him the secret that his parents died making MC agitated and autism regress and ML very mad. Ring a bell?
hmm the one I recall, MC is a painter and was later embroiled in a plagiarism scandal. would also like to know the title of the one ur looking for
The one you are looking for is not BL but BG, it is Quick Transmigration: Heroine Arrives, Woman Rapidly Retreats! and it is the Autistic Piano Girl vs. Private Tutor (Chapters 204 – 234) Arc
It kinda reminds me of one of the arcs from "please go easy on me villain" I think that was the name. It has been a long time since I've read it and it has so many chapters I can't remember if this is the one.
