Title of this webtoon?

It's an isekai set in modern life. The protag is a man that was pianist forced to give up because of an injury / lack of improvement (I don't remember). He died and woke up in the body of an European girl that was in a coma. I don't remember if the girl was German, Belgian, Russian, or something else... I just remember the protag had to study the language after the switch. Anyways very rich white girl that used to be a horrible person. From then he started to study the piano. And ofc was considered a genius even if he wasn't in fact he went to the academy of sort to improve..
