Anyone know the title?

This bl came to mind recently but I can’t remember the title nor find it. I’m also not sure if my memories of the characters and plot are correct but it goes along the lines of something like this. The uke is a student from Korea and plays the piano?? He has teleporting abilities and one day while messing around he teleports into some rich dude’s mansion forest backyard in Europe and landed on top of some pond. The rich blonde dude fell at first sight and then the uke would start frequently teleporting to visit him. And then one day they got into some argument or something and when the uke teleported back to Korea he found out he lost his teleporting abilities. So this whole time skip thing happens and blah blah blah… please let me know if this all sounds familiar I know it’s kind of messy haha anyways thanks!!!
