Help meeee

I literally read this Bl like not too long ago but I can’t remember the name and I NEED to catch up with it Bc I cannot stand leaving something unread when I start reading it. It’s about the uke who is a pianist and the seme who is a swimmer (who secretly listens to use playing piano). The Ike can’t play piano cuz he missed a note in front of audience and thinks he causes the ppl around him to be miserable bc he’s good at playing piano. Plz help me omg. The title was like the seas nocturne or something but it doesn’t show up when I search it.
