Ooooh this sounds interesting!! curious what this is. Commenting just so I could be updated too
this is exactly the start of love is an illusion
It is not the manhwa love is an illusion. it had a different art style. The seme is a well known composer, pianist or violinist where he has sex with the uke because he looked naive. The seme then repeated to have sex with the uke since the uke usually inspires him to write music. In the manhwa it did not show that the seme liking the uke at the start.
The manhwa uses words like cressendo, stacco or something similar to that kind of musical terms.
I have already found the manhwa. It is named Kiss the Piano. The correct summary for the story is the Mc is a normal person who incidentally attends a party where he hears the ML play the piano and was demanded to have sex as payment for listening. ML then pursues mc as a fuck buddy to recover mentally before piano performances since ML has performance anxiety.
the story is about a horny musician seme who writes music after sex. he has sex with uke and suddenly gets inspired to write music.
This is not given or FLASHLIGHT.
Note: If i remembered correctly the title either used an italian word used in music or I misremembered words said by the seme.
