I think Kanbe Akira has similar story. Search for that mangaka's work...
It's not yaoi (I think) but it's by yoneda kou, who also did seazuru

I remember reading a yaoi (or shonen ai or maybe just shonen in general?) about crime investigation. The uke has synesthesia, he could see when someone is lying and that's how he managed to catch the culprit.
The last time i read that it only had 1 chapter, and now i can't remember the name.. Pls help..
